Low Power Consumption, CMOS LDO
  • SKU
    WL2815

The WL2815 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 level of cost effective performance in cellular phones, laptop and notebook computers, and other portable devices.

The WL2815 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 WL2815 regulators are available in DFN1x1-4L packages. Standard products are Pb-free and Halogen free products.
