AP2213 Datasheet | BCD Semiconductor

Description The AP2213 is a 500m A output current fixed voltage regulator which provides low noise, very low dropout voltage (typically 350m V at 500m A), very low standby current (1µA maximum) and excellent power supply ripple rejection (PSRR 75d B at 100Hz) in battery powered applications, such as handsets and PDAs and in noise sensitive applications, such as RF electronics. The AP2213 features individual logic patible 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 AP2213 has 2.5V, 3.0V and 3.3V versions. The AP2213 is available in TO-252-2 (1) and SOIC-8 packages.
