1 / 19 page  150mA RF ULDO REGULATOR WITH ERROR FLAG AP2203 Preliminary Datasheet 1 Mar. 2006 Rev. 1. 0 BCD Semiconductor Manufacturing Limited General Description 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. 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.
