The WL2811EA series is a high accuracy, low noise, high speed, high PSRR, 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 WL2811EA 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 WL2811EA regulators are available in standard SOT-23-5L Package. Standard products are Pb-free and Halogen-free.

Applications
– MP3/MP4 Players
– Cellphones, radiophones, digital cameras
– Bluetooth, wireless handsets
– Other portable electronic devices
