General Description
AS78LXX General 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) and SOT-89-3 packages.
