AP138

300mA Low-Noise CMOS LDO

Features

General Descriptions

- Very low dropout voltage

The AP138 is a positive voltage linear regulator

utilizing CMOS technology. The features that

include low quiescent current (30µA typ.), low

dropout voltage, and high output voltage accuracy,

make it ideal for battery applications. EN input

connected to CMOS has low bias current. The

space-saving SOT23-5L package is attractive for

“Pocket” and “Hand Held” applications.

- Low current consumption: Typ.30µA, Max. 35µA

- Output voltage: 1.8V, 2.5V, 2.8V, 3.0V and 3.3V

- High accuracy output voltage: ±1.5%

- Guaranteed 300mA output

- Input range up to 7.0V

- Thermal shutdown

- Current limiting

- Stability with low ESR capacitors

- Factory pre-set output voltages

- Low temperature coefficient

- Pb-free package: SOT23-5L

This rugged device has both thermal shutdown, and

current limit protections to prevent device failure

under the “Worst” operating conditions.

In a low noise, regulated supply application, a

1000pF capacitor is necessary to be placed in

between Bypass and Ground.

Applications

- Battery-powered devices

- Personal communication devices

- Home electric/electronic appliances

- PC peripherals

The AP138 is stable with a low ESR output

capacitor of 1.0µF or greater.
