Regulator for RF and Analog Circuits

Descriptions

The WL2863D is a linear regulator capable of supplying

250-mA output current. Designed to meet the requirements

of RF and analog circuits, the WL2863D device provides low

noise, high PSRR, low quiescent current and very good

load /line transients.

The device is designed to work with a 1μF input and 1μF

output ceramic capacitor (no separate noise Operation

bypass capacitor is required).

DFN1X1-4L

VIN

The WL2863D regulators are available in standard

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

Halogen-free.
