Description

The SN78xxx 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 SN78xxx series can be used with external components to

obtain adjustable voltages and Currents.
