Overview

The WL2825D series of CMOS low dropout regulators are designed specifically for portable battery-powered applications which require ultra-low quiescent current. The ultra-low consumption of typ. 600 nA ensures long battery life and dynamic transient boost feature improves device transient response for wireless communication applications.

The device is designed to work with a 1 μF input and 1 μF output ceramic capacitor (no separate noise Operation bypass capacitor is required).

The WL2825D regulators are available in standard DFN1x1-4L Package. Standard products are Pb-free and Halogen-free.

Applications
- Battery Powered Equipment
- Portable Communication Equipment
- Cameras, Image Sensors and Camcorders
