150mA RF ULDO REGULATOR AP2202

Data Sheet

Jul. 2011 Rev. 2. 2 BCD Semiconductor Manufacturing Limited

General Description

The AP2202 is a 150mA ULDO regulator which pro-

vides very low noise, ultra low dropout voltage

(typically 165mV at 150mA), very low standby current

µA 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 AP2202 also features 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 pro-

tection.

The AP2202 has adjustable, 2.5V, 2.6V, 2.8V, 3.0V and

3.3V versions.

The AP2202 is available in space saving SOT-23-5 and

SOT-89 packages.
