WL2803E Ultra low dropout, 500mA, CMOS LDO WL2803E Http://www.sh-willsemi.com Descriptions The WL2803E series are ultra low dropout, Low quiescent current, high PSRR CMOS LDO. The dropout voltage is 130mV (Typ.) at 500mA load current. Using CMOS construction, the quiescent current consumed by the WL2803E is typically 150uA over the entire input voltage range, making it attractive for consumer, networking applications that demand high output current. The WL2803E series are available in wide output voltage range version from 1.2V to 3.3V with 0.1V step.
