General Description
The AS7805A is a three terminal positive regulator
designed for a wide variety of applications including
local, on-card regulation.
The AS7805A is complete with internal current limit-
ing, thermal shutdown protection, and safe-area com-
pensation which make it virtually immune from output
overload. If adequate heat sinking is provided, this IC
can deliver output current up to 1A.
The AS7805A is available in TO-220-3 and TO-252-2
(1) packages.
