AP2210
300mA RF ULDO REGULATOR
Description
Pin Assignments
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.
