Data Sheet
1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR
General Description
The AS78XX series are three terminal positive regula-
tors designed for a wide variety of applications includ-
ing local, on-card regulation.
The AS78XX are complete with internal current limit-
ing, thermal shutdown protection, and safe-area com-
pensation which make them virtually immune from
output overload. If adequate heat sinking are provided,
these regulators can deliver output currents up to 1A.
The AS78XX are available in TO-220-3 and TO-252-2
(1) packages.
