Internal Power Supply

Power supply for internal circuit.

In case maximum power dissipation exceeds or when the junction

temperature rises and the chip temperature (Tj) exceeds the heating

protection set temperature. The TSD protection circuit detects this

and forces the gate of output MOSFET to turn off in order to protect

the device from overheating. (Typ: 175 °C) When the junction

temperature decreases to low, the thermal Shutdown protection is

released and the output turns on automatically.

If the output current increases higher than the maximum output

current, it is limited by Over Current Protection in order to protect the

device from a damage caused by an over current. (Typ: 900 mA)

While this block is operating, the output voltage may decrease

because the output current is limited.

OCP

Over Current Protection

If an abnormal state is removed and the output current value returns

to normal, the output voltage also returns to normal state.

DISCHARGE Output Discharge Function Output pin is discharged when EN = “LOW” input or TSD is detected.

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit

between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is

operated over the absolute maximum ratings.

Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the

properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance and power dissipation taken into

consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating.

(Note 1) Do not exceed Tjmax.

(Note 5) If the inductance of power supply line is high, adjust input capacitor value in order to lower the input impedance.

A lower input impedance can bring out the ideal characteristic of IC as much as possible.

It also has the effect of preventing the voltage-drop at the input line.

(Note 6) Set capacitor value which do not fall below the minimum value. This value needs to consider the temperature characteristics and DC bias

characteristics.

(Note 7) It is recommended to use ceramic capacitors that have low ESR characteristics for the phase compensation.

In case of using electrolytic capacitor or ceramic capacitor with large ESR (> 100 mΩ), note that ceramic capacitor with 1 μF and more must be

connected near VOUT pin in parallel.

Application and Implementation

Notice: The following information is given as a reference or hint for the application and the implementation. Therefore, it does

not guarantee its operation on the specific function, accuracy or external components in the application. In the

application, it shall be designed with sufficient margin by enough understanding about characteristics of the external

components, e.g. capacitor, and also by appropriate verification in the actual operating conditions.

Selection of External Components

Input Pin Capacitor

In order to fully demonstrate the performance of this IC, it is recommended that the input capacitor be placed as close as

possible to the input pin and the GND pin without being affected by mounting impedance, etc., and that it be laid out on the

same mounting surface. In this case, a capacitor with a capacitance value of 0.1 μF (Min) or higher is recommended.

Depending on the layout of the peripheral components, including this IC, from the input power supply, if the distance from

the input power supply is too far or the impedance of the input side is too high, for example, the current supply due to the

load response of the IC cannot be withstood, and the output voltage may become unstable due to fluctuations in the input

voltage. In such a case, it is necessary to use a large capacitor to prevent the input voltage from dropping. Select the

capacitance of the input pin capacitor according to the line impedance between the power smoothing circuit and the input

pin, and the load response required by the application.

In addition, the consideration should be taken as the input pin capacitor, to prevent an influence to the regulator’s

characteristic from the deviation or the variation of the input capacitor’s characteristic. All input capacitors mentioned above

are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %, e.g. X7R,

X8R) with being satisfied high absolute maximum voltage rating based on EIA standard.

Output Pin Capacitor

The output capacitor is mandatory for the regulator in order to realize stable operation. The output capacitor with

capacitance value of 1 μF (Min) or higher and ESR up to 100 mΩ (Max) must be required between the output pin and the

GND pin.

A proper selection of appropriate both the capacitance value and ESR for the output capacitor can improve the transient

behavior of the regulator and can also keep the stability with better regulation loop. The correlation of the output capacitance

value and ESR is shown in the graph on the next page as the output capacitor’s capacitance value and the stability

region for ESR. As described in this graph, this regulator is designed to be stable with ceramic capacitors as of MLCC,

with the capacitance value from 1 μF to 500 μF and with ESR value within almost 0 Ω to 100 mΩ. The frequency range of

ESR can be generally considered at around 1 MHz.

Note that the provided the stable area of the capacitance value and ESR in the graph is obtained under a specific set of

conditions which is based on the measurement result in single IC on our board with a resistive load. In the actual

environment, the stability is affected by wire impedance on the board, input power supply impedance and also loads

impedance. Therefore, note that a careful evaluation of the actual application, the actual usage environment and the actual

conditions should be done to confirm the actual stability of the system.

Generally, in the transient event which is caused by the input voltage fluctuation or the load fluctuation beyond the gain

bandwidth of the regulation loop, the transient response ability of the regulator depends on the capacitance value of the

output capacitor. Basically the capacitance value of 1 μF (Min) or higher for the output capacitor is recommended as shown

in the table on Output Capacitance C_OUT, ESR Available Area. Using bigger capacitance value can be expected to

improve better the transient response ability in a high frequency. Various types of capacitors can be used for the output

capacitor with high capacity which includes electrolytic capacitor, electro-conductive polymer capacitor and tantalum

capacitor. Noted that, depending on the type of capacitors, its characteristics such as ESR (≤ 100 mΩ) absolute value

range, a temperature dependency of capacitance value and increased ESR at cold temperature needs to be taken into

consideration. When using capacitor with large ESR (≤ 100 mΩ) , note that ceramic capacitor with 1 µF or higher must be

connected in parallel to keep stability. In this case, the total capacitance should be less than 500 µF.

In addition, the same consideration should be taken as the input pin capacitor, to prevent an influence to the regulator’s

characteristic from the deviation or the variation of the external capacitor’s characteristic. All output capacitors mentioned

above are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %,

e.g. X7R, X8R) with being satisfied high absolute maximum voltage rating based on EIA standard. These capacitors should

be placed close to the output pin and mounted on the same board side of the regulator not to be influenced by implement

impedance.

Surge Voltage Protection for Linear Regulators

The following shows some helpful tips to protect ICs from possible inputting surge voltage which exceeds absolute

maximum ratings.

Positive Surge to the Input

If there is any potential risk that positive surges higher than absolute maximum ratings, it is applied to the input, a

Zener Diode should be inserted between the VIN pin and the GND to protect the device as shown in Figure 56.

Reverse Voltage Protection for Linear Regulators

A linear regulator which is one of the integrated circuit (IC) operates normally in the condition that the input voltage is

higher than the output voltage. However, it is possible to happen the abnormal situation in specific conditions which is

the output voltage becomes higher than the input voltage. A reverse polarity connection between the input and the output

might be occurred or a certain inductor component can also cause a polarity reverse conditions. If the countermeasure

is not implemented, it may cause damage to the IC. The following shows some helpful tips to protect ICs from the reverse

voltage occasion.

Protection against Reverse Input/Output Voltage

In the case that MOSFET is used for the pass transistor, a parasitic body diode between the drain-source generally

exists. If the output voltage becomes higher than the input voltage and if its voltage difference exceeds V_Fof the body

diode, a reverse current flows from the output to the input through the body diode as shown in Figure 58. The current

flows in the parasitic body diode is not limited in the protection circuit because it is the parasitic element, therefore

too much reverse current may cause damage to degrade or destroy the semiconductor elements of the regulator.

Protection against Reverse Input/Output Voltage – continued

An effective solution for this problem is to implement an external bypass diode in order to prevent the reverse current

flow inside the IC as shown in Figure 59. Especially in applications where the output voltage setting is high and a

large output capacitor is connected, be sure to consider countermeasures for large reverse current values. Note that

the bypass diode must be turned on prior to the internal body diode of the IC. This external bypass diode should be

chosen as being lower forward voltage V_Fthan the internal body diode. It should to be selected a diode which has a

rated reverse voltage greater than the IC’s input maximum voltage and also which has a rated forward current greater

than the anticipated reverse current in the actual application.

Figure 59. Bypass Diode for Reverse Current Diversion

A Schottky Barrier Diode which has a characteristic of low forward voltage (V_F) can meet to the requirement for the

external diode to protect the IC from the reverse current. However, it also has a characteristic that the leakage (I_R)

caused by the reverse voltage is bigger than other diodes. Therefore, it should be taken into the consideration to

choose it because if I_Ris large, it may cause increase of the current consumption, or raise of the output voltage in the

light-load current condition. I_Rcharacteristic of Schottky Diode has positive temperature characteristic, which the

details shall be checked with the datasheet of the products, and the careful confirmation of behavior in the actual

application is mandatory.

Even in the condition when the input/output voltage is inverted, if the VIN pin is open as shown in Figure 60, or if the

VIN pin becomes high-impedance condition as designed in the system, it cannot damage or degrade the parasitic

element. It's because a reverse current via the pass transistor becomes extremely low. In this case, therefore, the

protection external diode is not necessary.

Protection against Input Reverse Voltage

When the input of the IC is connected to the power supply, accidentally if plus and minus are routed in reverse, or if

there is a possibility that the input may become lower than the GND pin, it may cause to destroy the IC because a

large current passes via the internal electrostatic breakdown prevention diode between the VIN pin and the GND

pin inside the IC as shown in Figure 61.

The simplest solution to avoid this problem is to connect a Schottky Barrier Diode or a rectifier diode in series to the

power supply line as shown in Figure 62. However, it increases a power loss calculated as V_Fx I_CC, and it also causes

the voltage drop by a forward voltage V_Fat the supply voltage while normal operation.

Generally, since the Schottky Barrier Diode has lower V_F, so it contributes to rather smaller power loss than rectifier

diodes. If IC has load currents, the required input current to the IC is also bigger. In this case, this external diode

generates heat more, therefore select a diode with enough margin in power dissipation. On the other hand, a reverse

current passes this diode in the reverse connection condition, however, it is negligible because its small amount.

Figure 63 shows a circuit in which a P-channel MOSFET is connected in series to the power. The body diode (parasitic

element) is located in the drain-source junction area of the MOSFET. The drop voltage in a forward connection is

calculated from the on state resistance of the MOSFET and the output current I_OUT. It is smaller than the drop voltage

by the diode as shown in Figure 62 and results in less of a power loss. No current flows in a reverse connection where

the MOSFET remains off in Figure 63.

If the gate-source voltage exceeds maximum rating of MOSFET gate-source junction with derating curve in

consideration, reduce the gate-source junction voltage by connecting resistor voltage divider as shown in Figure 64.

Protection against Reverse Output Voltage when Output Connect to an Inductor

If the output load is inductive, electrical energy accumulated in the inductive load is released to the ground at the

moment that the output voltage is turned off. IC integrates ESD protection diodes between the IC output and ground

pins. A large current may flow in such condition finally resulting on destruction of the IC. To prevent this situation,

connect a Schottky Barrier Diode in parallel to the integrated diodes as shown in Figure 65.

Further, if a long wire is in use for the connection between the output pin of the IC and the load, confirm that the

negative voltage is not generated at the VOUT pin when the output voltage is turned off by observation of the

waveform on an oscilloscope, since it is possible that the load becomes inductive. An additional diode is required for

a motor load that is affected by its counter electromotive force, as it produces an electrical current in a similar way.

Thermal Design

This product exposes a frame on the back side of the package for thermal efficiency improvement. The power consumption

of the IC is decided by the dropout voltage condition, the load current and the current consumption. Refer to power dissipation

curves illustrated in Figure 66 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at

25 °C, chip junction temperature (Tj) can be very high depending on the input voltage and the load current. Consider the

design to be Tj ≤ Tjmax = 150 °C in whole operating temperature range.

Should by any condition the maximum junction temperature Tjmax = 150 °C rating be exceeded by the temperature increase

of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on

recommended PCB and measurement condition by JEDEC standard. Therefore, need to be careful because it might be

different from the actual use condition. Verify the application and allow sufficient margins in the thermal design by the following

method to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods.

1. The following method is used to calculate the junction temperature Tj with ambient temperature Ta.

Calculation Example (HTSOP-J8)

If V_IN= 13.5 V, V_OUT= 5.0 V, I_OUT= 200 mA, I_CC= 170 μA, the power consumption Pc can be calculated as follows:

the thermal impedance (Junction to Ambient) θ_JA= 26.0 °C/W (4-layer PCB)

푇푗 = 푇푎푚푎푥 + 푃_ꢀ× 휃_ꢆꢇ

= 85 °퐶 + 1.7 푊 × 26.0 °퐶/푊

= 129.2 °퐶

When operating the IC, the top center of case’s (mold) temperature T_T= 100 °C,

the Thermal Resistance (Junction to Top Center of Case) Ψ_JT= 10 °C/W (1-layer PCB)

푇푗 = 푇_ꢅ+ 푃_ꢀ× 훹

ꢆꢅ

= 100 °퐶 + 1.7 푊 × 10 °퐶/푊

= 117.0 °퐶

If it is difficult to ensure the margin by the calculations above, it is recommended to expand the copper foil area of the

board, increasing the layer and thermal via between thermal land pad for optimum thermal performance.

Operational Notes

1.

2.

Reverse Connection of Power Supply

Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when

connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply

pins.

Power Supply Lines

Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at

all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic

capacitors.

3.

4.

Ground Voltage

Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.

Ground Wiring Pattern

When using both small-signal and large-current ground traces, the two ground traces should be routed separately but

connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal

ground caused by large currents. Also ensure that the ground traces of external components do not cause variations

on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.

5.

6.

Operating Conditions

The function and operation of the IC are guaranteed within the range specified by the recommended operating

conditions. The characteristic values are guaranteed only under the conditions of each item specified by the electrical

characteristics.

Inrush Current

When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow

instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply.

Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing

of connections.

7.

Thermal Consideration

The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin

should be allowed in the thermal design. On the reverse side of the package this product has an exposed heat pad for

improving the heat dissipation. The amount of heat generation depends on the voltage difference between the input

and output, load current, and bias current. Therefore, when actually using the chip, ensure that the generated heat

does not exceed the Pd rating. If Junction temperature is over Tjmax (= 150 °C), IC characteristics may be worse due

to rising chip temperature. Heat resistance in specification is measurement under PCB condition and environment

recommended in JEDEC. Ensure that heat resistance in specification is different from actual environment.

8.

9.

Testing on Application Boards

When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject

the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should

always be turned off completely before connecting or removing it from the test setup during the inspection process. To

prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and

storage.

Inter-pin Short and Mounting Errors

Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in

damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.

Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and

unintentional solder bridge deposited in between pins during assembly to name a few.

10. Unused Input Pins

Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and

extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge

acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause

unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power

supply or ground line.

Operational Notes – continued

11. Regarding the Input Pin of the IC

This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them

isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a

parasitic diode or transistor. For example, (refer to figure below):

When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.

When GND > Pin B, the P-N junction operates as a parasitic transistor.

Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual

interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to

operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be

avoided.

12. Ceramic Capacitor

When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with

temperature and the decrease in nominal capacitance due to DC bias and others.

13. Thermal Shutdown Protection Circuit (TSD)

This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always

be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the

junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj

falls below the TSD threshold, the circuits are automatically restored to normal operation.

Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no

circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat

damage.

14. Over Current Protection Circuit (OCP)

This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This

protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should

not be used in applications characterized by continuous operation or transitioning of the protection circuit.
