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). This device is used in battery

powered applications, such as handsets and 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, overcurrent protection, overtemperature

protection, and reversed current 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 the space saving SOT-23-3 and SOT-23-5

packages.
