150mA RF ULDO REGULATOR AP2202

General Description

The AP2202 is a 150mA ULDO regulator which pro­vides very low noise, ultra low dropout voltage
(typically 165mV at 150mA), very low standby current
(1

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 pro­tection.

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.

tested in production.
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
