Low noise, High PSRR, High speed, CMOS

LDO

Descriptions

The WL2820X 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.

FBP1x1-4L

The WL2820X 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 WL2820X regulators are available in standard

FBP1x1-4L Package. Standard products are Pb-free

and Halogen-free.
