DATA SHEET

AAT3237

300mA MicroPower^TMLDO with PowerOK

General Description

Features

•

The AAT3237 MicroPower low dropout (LDO) linear regu-

lator is ideally suited for portable applications where low

noise, extended battery life, and small size are critical.

The AAT3237 has been specifically designed for low out-

put noise performance, fast transient response, and high

power supply rejection ratio (PSRR).

Low Dropout: 400mV at 300mA

Guaranteed 300mA Output

High Accuracy ±1.5%

70µA Quiescent Current

High Power Supply Ripple Rejection

Power-OK (POK) Output

Fast Line and Load Transient Response

Short-Circuit Protection

Over-Temperature Protection

Uses Low Equivalent Series Resistance (ESR) Ceramic

Capacitors

Shutdown Mode for Longer Battery Life

Low Temperature Coefficient

13 Factory-Programmed Output Voltages

SOT23 6-Pin or SC70JW 8-Pin Package

Other features include low quiescent current, typically

70µA, and low dropout voltage, typically less than

400mV at full output current. The device is output short-

circuit protected and has a thermal shutdown circuit for

additional protection under extreme conditions.

•

The AAT3237 also features a low-power shutdown mode

for extended battery life. A Power-OK open-drain output

signals when V_OUTis in regulation.

The AAT3237 is available in a Pb-free, space-saving

6-pin SOT23 or 8-pin SC70JW package in 13 factory-

programmed voltages: 1.2V, 1.5V, 1.8V, 2.0V, 2.3V, 2.5V,

2.7V, 2.8V, 2.85V, 2.9V, 3.0V, 3.3V, or 3.5V.
