ANALOG DEVICES ADP222ACPZ-1825-R7 LDO Voltage Regulator, Fixed, 2.5 to 5.5V in, 2.5V / 0.3A Out, LFCSP-UD-EP-8

ADP222ACPZ-1825-R7 is a high PSRR voltage regulator. This fixed dual output ADP222 combines high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator that is ideally suited for wireless applications with demanding performance and board space requirements. The ADP222 maintains power supply rejection greater than 60dB for frequencies as high as 100KHz while operating with a low headroom voltage. The ADP222 offers much lower noise performance than competing LDOs without the need for a noise bypass capacitor. Overcurrent and thermal protection circuitry prevent damage in adverse conditions. Application includes portable and battery-powered equipment, portable medical devices, post dc-to-dc regulation, point of sale terminals, credit card readers, automatic meter readers, wireless network equipment.
