WL2805 WL2805 Low power consumption, CMOS LDO Http://www.sh-willsemi.com Descriptions The WL2805 series are low dropout linear regulators and optimized to provide a high performance solution for battery power system to deliver low quiescent current. The devices offer a new SOT-23-3L SOT-23-5L level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices. The WL2805 series are designed to make use of low cost ceramic capacitors which ensure the stability of the output current, and enhance the efficiency in order to prolong the battery life of those portable devices. The WL2805 regulators are available WL2805N** in WL2805E** SOT-23-3L packages. Standard products are Pb-free Pin Configuration (Top View) and Halogen free products.
