MCP1804

150 mA, 28V LDO Regulator With Shutdown

Features

Description

• 150 mA Output Current

The MCP1804 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 150 mA of

current while consuming only 50 µA of quiescent

current (typical, 1.8V ≤ V_OUT≤ 5.0V). The input

operating range is specified from 2.0V to 28.0V.

• Low Drop Out Voltage, 260 mV typical @ 20 mA,

V_R= 3.3V

• 50 µA Typical Quiescent Current

• 0.01 µA Typical Shutdown Current

• Input Operating Voltage Range: 2.0V to 28.0V

The MCP1804 is capable of delivering 100 mA with

only 1300 mV (typical) of input to output voltage

differential (V_OUT= 3.3V). The output voltage tolerance

of the MCP1804 at +25°C is a maximum of ±2%. Line

regulation is ±0.15% typical at +25°C.

• Standard Output Voltage Options

(1.8V, 2.5V, 3.0V, 3.3V, 5.0V, 10.0V, 12.0V)

• Output Voltage Accuracy: ±2%

• Output voltages from 1.8V to 18.0V in 0.1V

increments are available upon request

The LDO input and output is stable with 0.1 µF of input

and output capacitance. Ceramic, tantalum or

aluminum electrolytic capacitors can all be used for

input and output. Overcurrent limit with current foldback

to 40 mA (typical) provides short-circuit protection.

A shutdown (SHDN) function allows the output to be

enabled or disabled. When disabled, the MCP1804

draws only 0.01 µA of current (typical).

• Stable with Ceramic output capacitors

• Current Limit Protection With Current Foldback

• Shutdown pin

• High PSRR: 50 dB typical @ 1 kHz

3.3

Shutdown Input (SHDN)

Connect V_INto the input unregulated source voltage.

Like all low dropout linear regulators, low source

impedance is necessary for the stable operation of the

LDO. The amount of capacitance required to ensure

low source impedance will depend on the proximity of

the input source capacitors or battery type. For most

applications, 0.1 µF to 1.0 µF of capacitance will

ensure stable operation of the LDO circuit. The type of

capacitor used can be ceramic, tantalum or aluminum

electrolytic. The low ESR characteristics of the ceramic

will yield better noise and PSRR performance at

high-frequency.

The SHDN input is used to turn the LDO output voltage

on and off. When the SHDN input is at a logic-high

level, the LDO output voltage is enabled. When the

SHDN input is pulled to a logic-low level, the LDO

output voltage is disabled and the LDO enters a low

quiescent current shutdown state where the typical

quiescent current is 0.01 µA. The SHDN pin does not

have an internal pullup or pulldown resistor. The SHDN

pin must be connected to either V_INor GND to prevent

the device from becoming unstable.

3.4

Regulated Output Voltage (V_OUT)

Connect V_OUTto the positive side of the load and the

positive terminal of the output capacitor. The positive

side of the output capacitor should be physically

located as close to the LDO V_OUTpin as is practical.

The current flowing out of this pin is equal to the DC

load current. For most applications, 0.1 µF to 1.0 µF of

capacitance will ensure stable operation of the LDO

circuit. Larger values may be used to improve dynamic

load response. The type of capacitor used can be

ceramic, tantalum or aluminum electrolytic. The low

ESR characteristics of the ceramic will yield better

noise and PSRR performance at high-frequency.

3.2

Ground Terminal (GND)

Regulator ground. Tie GND to the negative side of the

output and the negative side of the input capacitor.

Only the LDO bias current (50 to 60 µA typical) flows

out of this pin; there is no high current. The LDO output

regulation is referenced to this pin. Minimize voltage

drops between this pin and the negative side of the

load.

4.1

DETAILED DESCRIPTION

Output Regulation

The MCP1804 requires a minimum output capacitance

of 0.1 µF to 1.0 µF for output voltage stability. Ceramic

capacitors are recommended because of their size,

cost and environmental robustness qualities.

A portion of the LDO output voltage is fed back to the

internal error amplifier and compared with the precision

internal bandgap reference. The error amplifier output

will adjust the amount of current that flows through the

P-Channel pass transistor, thus regulating the output

voltage to the desired value. Any changes in input

voltage or output current will cause the error amplifier

to respond and adjust the output voltage to the target

voltage (refer to Figure 4-1).

Aluminum-electrolytic and tantalum capacitors can be

used on the LDO output as well. The output capacitor

should be located as close to the LDO output as is

practical. Ceramic materials X7R and X5R have low

temperature coefficients.

Larger LDO output capacitors can be used with the

MCP1804 to improve dynamic performance and power

supply ripple rejection performance. Aluminum-

electrolytic capacitors are not recommended for low

temperature applications of < -25°C.

4.2

Overcurrent

The MCP1804 internal circuitry monitors the amount of

current flowing through the P-Channel pass transistor.

In the event that the load current reaches the current

limiter level of 200 mA (typical), the current limiter

circuit will operate and the output voltage will drop. As

the output voltage drops, the internal current foldback

circuit will further reduce the output voltage causing the

output current to decrease. When the output is shorted,

a typical output current of 50 mA flows.

4.5

Input Capacitor

Low input source impedance is necessary for the LDO

output to operate properly. When operating from

batteries, or in applications with long lead length

(> 10 inches) between the input source and the LDO,

some input capacitance is recommended. A minimum

of 0.1 µF to 1.0 µF is recommended for most

applications.

4.3

Shutdown

For applications that have output step load

requirements, the input capacitance of the LDO is very

important. The input capacitance provides the LDO

with a good local low-impedance source to pull the

transient currents from in order to respond quickly to

the output load step. For good step response

performance, the input capacitor should be of

equivalent or higher value than the output capacitor.

The capacitor should be placed as close to the input of

the LDO as is practical. Larger input capacitors will also

help reduce any high-frequency noise on the input and

output of the LDO and reduce the effects of any

inductance that exists between the input source

voltage and the input capacitance of the LDO.

The SHDN input is used to turn the LDO output voltage

on and off. When the SHDN input is at a logic-high

level, the LDO output voltage is enabled. When the

SHDN input is pulled to a logic-low level, the LDO

output voltage is disabled and the LDO enters a low

quiescent current shutdown state where the typical

quiescent current is 0.01 µA. The SHDN pin does not

have an internal pullup or pulldown resistor. Therefore

the SHDN pin must be pulled either high or low to

prevent the device from becoming unstable. The

internal device current will increase when the device is

operational and current flows through the pullup or

pull-down resistor to the SHDN pin internal logic. The

SHDN pin internal logic is equivalent to an inverter

input.

4.6

Thermal Shutdown

The MCP1804 thermal shutdown circuitry protects the

device when the internal junction temperature reaches

the typical thermal limit value of +150°C. The thermal

limit shuts off the output drive transistor. Device output

will resume when the internal junction temperature falls

below the thermal limit value by an amount equal to the

thermal limit hysteresis value of +25°C.

FUNCTIONAL DESCRIPTION

The maximum rated continuous output current for the

MCP1804 is 150 mA.

The MCP1804 CMOS linear regulator is intended for

applications that need the low current consumption

while maintaining output voltage regulation. The

operating continuous load range of the MCP1804 is

from 0 mA to 150 mA. The input operating voltage

range is from 2.0V to 28.0V, making it capable of

operating from a single 12V battery or single and

multiple Li-Ion cell batteries.

A minimum output capacitance of 0.1 µF to 1.0 µF is

required for small signal stability in applications that

have up to 150 mA output current capability. The

capacitor type can be ceramic, tantalum or aluminum

electrolytic.

5.1

Input

The input of the MCP1804 is connected to the source

of the P-Channel PMOS pass transistor. As with all

LDO circuits, a relatively low source impedance

(< 10Ω) is needed to prevent the input impedance from

causing the LDO to become unstable. The size and

type of the capacitor needed depends heavily on the

input source type (battery, power supply) and the

output current range of the application. For most

applications

a 0.1 µF ceramic capacitor will be

sufficient to ensure circuit stability. Larger values can

be used to improve circuit AC performance.

MCP1804

The maximum continuous operating temperature

specified for the MCP1804 is +85°C. To estimate the

internal junction temperature of the MCP1804, the total

internal power dissipation is multiplied by the thermal

resistance from junction to ambient (Rθ_JA). The thermal

resistance from junction to ambient for the SOT-25 pin

package is estimated at 256°C/W.

Voltage Reference

Internal Power dissipation is the product of the LDO

output current times the voltage across the LDO

(V_INto V_OUT).

The MCP1804 can be used not only as a regulator, but

also as a low quiescent current voltage reference. In

many microcontroller applications, the initial accuracy

of the reference can be calibrated using production test

equipment or by using a ratio measurement. When the

initial accuracy is calibrated, the thermal stability and

line regulation tolerance are the only errors introduced

by the MCP1804 LDO. The low cost, low quiescent

current and small ceramic output capacitor are all

advantages when using the MCP1804 as a voltage

reference.

6.3.1.1

Device Junction Temperature Rise

The internal junction temperature rise is a function of

internal power dissipation and the thermal resistance

from junction to ambient for the application. The thermal

resistance from junction to ambient (Rθ_JA) is derived

from an EIA/JEDEC standard for measuring thermal

resistance for small surface mount packages. The EIA/

JEDEC specification is JESD51-7, “High Effective

Thermal Conductivity Test Board for Leaded Surface

Mount Packages”. The standard describes the test

method and board specifications for measuring the

thermal resistance from junction to ambient. The actual

thermal resistance for a particular application can vary

depending on many factors, such as copper area and

thickness. Refer to AN792, “A Method to Determine

How Much Power a SOT23 Can Dissipate in an

Application” (DS00792), for more information regarding

this subject.

Pulsed Load Applications

For some applications, there are pulsed load current

events that may exceed the specified 150 mA

maximum specification of the MCP1804. The internal

current limit of the MCP1804 will prevent high peak

load demands from causing non-recoverable damage.

The 150 mA rating is a maximum average continuous

rating. As long as the average current does not exceed

150 mA nor the max power dissipation of the packaged

device, pulsed higher load currents can be applied to

the MCP1804. The typical current limit for the

MCP1804 is 200 mA (T_A= +25°C).

NOTES:

DS22200A-page 34

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device

applications and the like is provided only for your convenience

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.

arising from this information and its use. Use of Microchip

devices in life support and/or safety applications is entirely at

the buyer’s risk, and the buyer agrees to defend, indemnify and

hold harmless Microchip from any and all damages, claims,

suits, or expenses resulting from such use. No licenses are
