Preliminary Datasheet 500mA 3-TERMINAL POSITIVE VOLTAGE REGULATOR General Description
The AZ78MXX 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 0.5A. The AZ78MXX series are available in two standard plastic packages: TO-220 and TO-252.
