100mA POSITIVE VOLTAGE REGULATOR

Description

The AS78LXX series are three terminal positive regulators designed

for a wide variety of applications including local, on-card regulation.

This series of regulators are complete with internal current limiting,

thermal shutdown protection, and safe-area compensation which

make them virtually immune from output overload. If adequate heat

sinking are provided, these regulators can deliver output currents up

to 100mA.

The AS78LXX series are available in TO-92 (bulk or ammo packing),

SOT-89 and SOIC-8 packages.
