AP2210K-2.5TRE1

AP2210K-2.5TRE1 is an AP2210 series 300mA RF 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). 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. This device is used in battery powered applications, such as handsets and PDAs and in noise sensitive applications, such as RF electronics. Applications also include cellular phones, cordless phones, wireless communicators, PDAs/palmtops, PC motherboards and consumer electronics.
