Low noise, High PSRR, High speed, CMOS

LDO

Descriptions

The WL2820D 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.

DFN1X1-4L

The WL2820D 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 WL2820D regulators are available in standard

DFN1x1-4L Package. Standard products are Pb-free

and Halogen-free.
