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
(1 µ A 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.
