AP131

300mA Low Dropout Linear Regulator with Shutdown

Features

General Descriptions

- Input voltage range is up to 7V

The AP131 is a 300mA, fixed output voltage, low

dropout linear regulator. The Device included pass

element, error amplifier, band-gap, current limit and

thermal shutdown circuitry. The device is ON when

EN pin is set to logic high level.

- Dropout voltage 400mV at 300mA output current

- Guaranteed 300mA output current.

- Internal R^on=1.5Ω PMOS draws no base current

- Low quiescent current 50µA

- Output voltage 2% accuracy, and 1.5V to 5V with

0.1V step

The characteristics of low dropout voltage and less

quiescent current make it good for some critical

current application, for example, some battery

powered devices. The typical quiescent current is

approximately 50µA from zero to maximum load.

Due to internal flexible design, result in extensively

fixed output voltage versions and make it

convenient to use for applications. Built-in

current-limit and thermal-shutdown functions

prevent any fault condition from IC damage. An

external capacitor can be connected to the BP pin

and reduce the output noise.

- Active low shutdown function (EN pin).

- Fast transient response

- Good load regulation

- Current limit and thermal shutdown protection

- SOT89-5L and SOT23-5L packages

Applications

- Wireless Communication

- Battery Powered device

- CD-ROM, DVD, and LAN Card

- PC peripheral
