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 (1
μA 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.
