AP2213

500mA LOW NOISE LDO REGULATOR

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). This device is

used 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, and reversed

current protection.

The AP2213 has 2.5V, 3.0V, and 3.3V versions.

The AP2213 is available in the TO-252-2 (3), SOIC-8, and SOT-223

packages.
