DATA SHEET

AAT3242

300mA/150mA Dual CMOS LDO Linear Regulator

Features

General Description

•

The AAT3242 is a dual low dropout linear regulator with

Power OK (POK) outputs. Two integrated regulators pro-

vide a high power 300mA output and a lower power

150mA output, making this device ideal for use with

microprocessors and DSP cores in portable products.

Two POK pins provide open drain output signals when

their respective regulator output is within regulation.

The AAT3242 has independent input voltage and enable

pins for increased design flexibility. This device features

a very low quiescent current (140µA typical) and low

dropout voltages (typically 200mV and 400mV at the full

output current level), making it ideal for portable appli-

cations where extended battery life is critical. The

AAT3242 has complete over-current/short-circuit and

over-temperature protection circuits to guard against

extreme operating conditions.

High/Low Current Outputs, 300mA/150mA

Low Dropout:

LDO A: 400mV at 300mA

LDO B: 200mV at 150mA

High Output Voltage Accuracy: ±1.5%

High PSRR: 65dB at 1kHz
