The S78xx series are three-terminal positive regulators providing over 1A output current with internal current limiting, thermal shutdown and safe area protection. These regulators are useful in a wide range of applications. Although they are just fixed voltage regulators, the S78xx series can be used with external components to obtain adjustable voltages and currents.
The S78xxPI series are three‑terminal positive regulators offering over 1 A output current with internal current limiting, thermal overload protection and safe‑area protection. They are intended for a wide range of applications and can be used with external components for adjustable voltages.
The document provides ordering information, mechanical dimensions, pin connections, absolute maximum ratings, detailed electrical characteristics for each voltage version, and characteristic curves illustrating performance across temperature and load conditions.
