Preliminary Datasheet

150mA RF ULDO REGULATOR WITH ERROR FLAG

AP2203

General Description

Features

The AP2203 is a 150mA ULDO regulator, which pro-

vides ultra low dropout voltage (typically 165mV at

150mA), very low quiescent current (1µA maximum)

in shutdown mode and excellent power supply ripple

rejection (PSRR 75dB at 100Hz) in battery powered

applications, such as handsets and PDAs and in noise

sensitive applications, such as RF electronics.

DROP

High Output Accuracy: ±1%

Good Ripple Rejection Ability: 75dB at 100Hz

and I =100µA

OUT

The AP2203 also features an undervoltage monitor

with an error flag output, logic compatible enable/shut-

down control inputs, a low power shutdown mode for

extended battery life, over current protection, over

temperature protection as well as reversed-battery pro-

tection.

The AP2203 has 2.5V, 3.0V and 3.3V versions.

The AP2203 is available in space saving 5-pin SOT-

23-5 package.
