AP2202

150mA RF ULDO REGULATOR

Description

The

DIODES™ AP2202 is a 150mA ULDO regulator which provides

very low noise, ultra-low dropout voltage (typically 165mV at 150mA),

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 AP2202 also features logic-compatible enable/shutdown control

inputs, a low power shutdown mode for extended battery life,

overcurrent protection, over temperature protection, and reversed

current protection.

The AP2202 has adjustable 2.5V, 2.6V, 2.8V, 3.0V, and 3.3V

versions.

The AP2202 is available in the space-saving SOT-23-5 and SOT-89

packages.
