General Description
The AS78LXX series are three terminal positive regu-
lators 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 cur-
rents up to 100mA.
The AS78LXX series are available in TO-92 and SOT-
89-3 packages.
