AP2213

Data Sheet 500mA LOW NOISE LDO REGULATOR General Description The AP2213 is a 500mA output current fixed voltage regulator which provides low noise, very low dropout voltage (typically 350mV at 500mA), very low standby current (1µA maximum) 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 AP2213 features individual 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 AP2213 has 2.5V, 3.0V and 3.3V versions. The AP2213 is available in TO-252-2 (1) and SOIC-8 packages.
