Low Power Low Noise LDO

CMOS Voltage Regulator

SE5509

Description

Features



Typical 200mV Dropout Voltage at 150mA.

The SE5509 series of fixed output low dropout

Fast Enable Turn-On Time of 20μs (Typ.)

linear regulators are designed for portable battery

powered applications, which require low power

consumption, low noise environment, and low

dropout voltage. Each device contains a bandgap

voltage reference, an error amplifier, a PMOS

power transistor, and resistors for setting output

voltage, and current limit and temperature limit

protection circuits.

Excellent Line and Load Regulation.

High Accuracy Output Voltage of 2%.

Ultra-Low Ground Current at 20μA (Typ.)

Disable Current Less than 0.1μA (Typ.)

Over Current and thermal Protection.

No Reverse Current.

Standard SOT-23-5L and TSOP-5 Package.

Application

The SE5509 has been designed to be used

with low cost capacitors and requires a minimum

output capacitor of 1.0μF. The output voltages

range from 1.3V to 4.4V in 100mV increments.

Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0,

and 3.3V.
