AP2210
300mA RF ULDO REGULATOR
Description
The AP2210 is a 300mA ULDO regulator which provides very low
noise, ultra low dropout voltage (typically 250mV at 300mA), very low
standby current (1µA maximum) and excellent power supply ripple
rejection (PSRR 75dB at 100Hz) in battery powered applications,
such as handsets, PDAs and in noise sensitive 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-battery 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.

Note 4:
Dropout voltage is 250mV when T

o
C. In order to obtain a normal output voltage, V
OUT
+0.25V is the minimum input voltage which will result a low
PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is V
OUT
+1V to 13.2V. For AP2210-3.0 version, its input voltage can
be set from 4V (V
OUT
+1V) to 13.2V.
