general Description

The S

P78MXX 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 S

P78MXX series are available in two standard plastic packages: TO-220 and TO-252.
