AP2202K-ADJTRG1

AP2202K-ADJTRG1 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. It also features logic-compatible enable/shutdown control inputs, a low-power shutdown mode for extended battery life, overcurrent protection, overtemperature protection, and reverse current protection. Applications include cellular phones, cordless phones, digital still cameras, wireless communicators, PDAs/palmtops, PC motherboards, and consumer electronics.
