AP2210N-3.3TRG1

AP2210N-3.3TRG1 is a 300mA ULDO regulator that 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. It also features individual 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, wireless communicators, PDAs/palmtops, PC motherboards, and consumer electronics.
