General Description
Features
AP2213
The AP2213 is a 500mA output current fixed voltage _{· Up to 500mA Output Current}
regulator which provides low noise, very low dropout _{· Low Standby Current}
voltage (typically 350mV at 500mA), very low
standby current (1µA maximum) and excellent power
supply ripple rejection (PSRR 75dB at 100Hz) in bat-
