WL2801E Low noise, High PSRR, High speed, CMOS LDO Descriptions The WL2801E series is a high accuracy, low noise, high speed, low dropout CMOS Linear regulator with high ripple rejection. The devices offer a new level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices. The current limiter's fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin. The WL2801E regulators are available in standard SOT-23-5L packages. Standard products are Pb-free and Halogen-free. Features z Input voltage : 2.7V~5.5V z Output range : 1.2V~3.3V z Output current : 200mA (Up to 300mA Typ.) z PSRR : 75dB @ 217Hz z Dropout voltage : 170mV @ IOUT=200mA z Quiescent current : 70ȝA Typ.
