WL2836D WL2836D Low noise, High PSRR, High speed, CMOS LDO Http://www.sh-willsemi.com Descriptions The WL2836D series is a high accuracy, low noise, high speed, high PSRR, low dropout CMOS Linear regulator with high ripple rejection. The devices offer a DFN1x1-4L new level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices. The WL2836D has the fold-back maximum output current which depends on the output voltage. So the current limit functions both as a short circuit protection and as an output current limiter. The WL2836D regulators are available in standard Pin Configuration (Top View) DFN1x1-4L Package. Standard products are Pb-free and Halogen-free.
