WL2808E Low noise, High PSRR, High speed, CMOS LDO Descriptions The WL2808E 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 WL2808E regulators are available in standard SOT-23-5L packages. Standard products are Pb-free and Halogen-free. Features  Input voltage : 2.5V~5.5V  Output range : 1.2V~3.3V  Output current : 200mA (@VOUT<2V)(Typ.)   PSRR 300mA (@VOUT>2V)(Typ.
