WL2808E18-5/TR

WL2808E WL2808E Low noise, High PSRR, High speed, CMOS LDO http://www.omnivision-group.com/ 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. SOT-23-5L 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.
