WL2863E
Ultra-Low Noise, High PSRR LDO, 250mA Linear
Regulator for RF and Analog Circuits
Http://www.sh-willsemi.com
Descriptions
The WL2863E is a linear regulator capable of
supplying 250-mA output current. Designed to meet
the requirements of RF and analog circuits, the
WL2863E 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).
SOT-23-5L
The WL2863E regulators are available in standard
SOT-23-5L Package. Standard products are Pb-free
and Halogen-free.
