Preliminary Datasheet 3-TERMINAL POSITIVE LINEAR
REGULATORS General Description
The AZ78XX series are monolithic integrated circuits designed as fixed-voltage
regulators 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 1.0A. The AZ78XX series are available in two standard plastic packages: TO-220 and TO-252.
AZ78XX
Features
