500mA LOW NOISE LDO REGULATOR AP2213

Data Sheet

Dec. 2012 Rev. 2. 0 BCD Semiconductor Manufacturing Limited

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 bat-

tery powered applications, such as handsets and PDAs

and in noise sensitive applications, such as RF elec-

tronics.

The AP2213 features individual logic compatible

enable/shutdown control inputs, a low power shut-

down mode for extended battery life, over current pro-

tection, 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), TO-252-2

(3), SOIC-8 and SOT-223 packages.
