AP2203 - BCD Semiconductor

AP2203 RF ULDO REGULATOR

The AP2203 is a 150mA ULDO regulator, which provides 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. The AP2203.

Features

an undervoltage monitor with an error flag output, logic compatible enable/shutdown control inputs, a low power shutdown mode for extended battery life, over current protection, over temperature protection as well as reversed-battery protection. The AP2203 has 2.5V, 3.0V and 3.3V versions. The AP2203 is available in space saving 5-pin SOT23-5 package. AP2203 Features
