The SGM2036 is a low noise, low voltage and low

dropout voltage linear regulator. It is capable of

supplying 300mA output current with typical dropout

voltage of only 165mV. The operating input voltage

range is from 1.6V to 5.5V. The output voltage range is

from 0.8V to 5.0V in fixed output version. For

adjustable output version, the output voltage can be

adjusted from 0.8V to 5.0V by using external resistors.

 Adjustable Output from 0.8V to 5.0V

 300mA Guaranteed Output Current

 Output Voltage Accuracy: ±2.5% at +25℃

 Low Dropout Voltage: 165mV (TYP) at 300mA

 Low Supply Current: 20μA (TYP)

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2036 has automatic discharge

function to quickly discharge V_OUTin the disabled status.

 Shutdown Supply Current: 0.01μA (TYP)

 Short Start-Up Time

 Short Auto-Discharge Function

 Thermal Shutdown Protection

Package Thermal Resistance

Stresses beyond those listed in Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to

absolute maximum rating conditions for extended periods

may affect reliability. Functional operation of the device at any

conditions beyond those indicated in the Recommended

Operating Conditions section is not implied.

ESD SENSITIVITY CAUTION

This integrated circuit can be damaged if ESD protections are

not considered carefully. SGMICRO recommends that all

integrated circuits be handled with appropriate precautions.

Failure to observe proper handling and installation procedures

can cause damage. ESD damage can range from subtle

performance degradation to complete device failure.

Precision integrated circuits may be more susceptible to

damage because even small parametric changes could

cause the device not to meet the published specifications.

Regulator Output Pin. It is recommended to use a ceramic capacitor with

effective capacitance in the range of 0.5μF to 10μF to get good power

supply decoupling. This ceramic capacitor should be placed as close as

Enable Pin. Drive EN high to turn on the regulator. Drive EN low to turn

off the regulator. This pin must be pulled high by an external resistor

connected to IN pin if EN pin is not used.

Input Voltage Supply Pin. It is recommended to use a 1μF or larger

ceramic capacitor from IN pin to ground. This ceramic capacitor should

be placed as close as possible to IN pin.

Reference-Noise Bypass Pin (fixed voltage version only). Bypass with an

external capacitor C_BPcan reduce output noise to very low level. The

capacitor is recommended to be placed very close to the pin for high

PSRR.

Feedback Voltage Input Pin (adjustable voltage version only). Connect

this pin to the external resistor divider to adjust the output voltage. Place

the resistors as close as possible to this pin.

Exposed Pad. Connect it to GND internally. Connect it to a large ground

plane to maximize thermal performance; this pad is not an electrical

connection point.

300mA, Low Power

SGM2036

and Low Dropout RF Linear Regulator

APPLICATION INFORMATION

The SGM2036 is a low input voltage, ultra-low noise

and low dropout LDO and provides 300mA output

current. These features make the device a reliable

solution to solve many challenging problems in the

generation of clean and accurate power supply. The

high performance also makes the SGM2036 useful in a

variety of applications. The SGM2036 provides the

protection function for output overload, output short

-circuit condition and overheating.

When the EN pin voltage is lower than 0.4V, the device

is in shutdown state, there is no current flowing from IN

to OUT pins. In this state, the automatic discharge

transistor is active to discharge the output voltage

through a 50Ω (TYP) resistor.

When the EN pin voltage is higher than 1.5V, the device

is in active state, the input voltage is regulated to the

output voltage and the automatic discharge transistor is

turned off.

The SGM2036 provides an EN pin as an external chip

enable control to enable/disable the device. When the

regulator is in shutdown state, the shutdown current

consumes as low as 0.01μA (TYP).

The EN pin is pulled down by internal 0.8μA (TYP)

current source when the EN pin is floated. This current

source will ensure the SGM2036 in shutdown state and

reduce the power dissipation in system.

Input Capacitor Selection (C_IN)

Reverse Current

The pass transistor has an inherent body diode which

will be forward biased in the case when V_OUT> (V_IN

0.3V). If extended reverse voltage operation is

anticipated, external limiting might be appropriate.

The input decoupling capacitor is necessary to be

connected as close as possible to the IN pin for

ensuring the device stability. 1μF or greater X7R or

X5R ceramic capacitor is selected to get good dynamic

performance.

+

When V_INis required to provide large current

instantaneously, a large effective input capacitor is

required. Multiple input capacitors can limit the input

tracking inductance. Adding more input capacitors is

available to restrict the ringing and to keep it below the

device absolute maximum ratings.

Negatively Biased Output

When the output is negative voltage, the chip may not

start up due to parasitic effects. Ensure that the output

is greater than -0.3V under all conditions. If excessive

negatively biased output is expected in the application,

a Schottky diode can be added between the OUT pin

and GND pin.

Output Capacitor Selection (C_OUT

)

The output decoupling capacitor should be located as

close as possible to the OUT pin. 1μF or greater X7R or

X5R ceramic capacitor is selected to get good dynamic

performance. The minimum effective capacitance of

C_OUTthat SGM2036 can remain stable is 0.5μF. For

ceramic capacitor, temperature, DC bias and package

size will change the effective capacitance, so enough

margin of C_OUTmust be considered in design. Larger

capacitance and lower ESR C_OUTwill help improve the

load transient response and increase the high

frequency PSRR.

Output Current Limit and Short-Circuit

Protection

When overload events happen, the output current is

internally limited to 560mA (TYP). When the OUT pin is

shorted to ground, the short-circuit protection will limit

the output current to 200mA (TYP).

Thermal Shutdown

The SGM2036 can detect the temperature of die. When

the die temperature exceeds the threshold value of

thermal shutdown, the SGM2036 will be in shutdown

state and it will remain in this state until the die

temperature decreases to +140℃.

Enable Control

The SGM2036 uses the EN pin to enable/disable its

device and to deactivate/activate the output automatic

discharge function.
