1A 3-TERMINAL POSITIVE VOLTAGE REGULATOR
General Description
Features
AS78XXA
The AS78XXA series are three terminal positive
voltage regulators designed for a wide variety of appli-
cations including local, on-card regulation.
The AS78XXA are complete with internal current lim-
iting, 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 AS78XXA are available in TO-252-2 (1), TO-
252-2 (3), TO-252-2 (4), TO-220-3 and TO-220F-3
packages.
