WL2810

WL2810 Low noise, High PSRR, High speed, CMOS LDO Descriptions The WL2810 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 WL2810 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 WL2810 regulators are available in standard SOT-353 package and DFN1x1-4L Package. Standard products are Pb-free and Halogen-free.
