The 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) 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, over current protection, over temperature protection, as well as reversed-battery protection. The AP2202 has adjustable, 2.5V, 2.6V, 2.8V, 3.0V and 3.3V versions. The AP2202 is available in space saving SOT-23-5 and SOT-89 packages.
