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.

SOT-353

DFN1X1-4L

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.
