General Description
The AP2210 is a 300mA ULDO regulator which pro-
vides very low noise, ultra low dropout voltage
(typically 250mV at 300mA), 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, PDAs and in noise sen-
sitive applications, such as RF electronics.
The AP2210 also features individual 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-bat-
tery protection.
The AP2210 has 2.5V, 2.8V, 3.0V, 3.3V, 3.6V, 4.0V,
5.0V and ADJ versions.
The AP2210 is available in space saving SOT-23-3 and
SOT-23-5 packages.
