S78xxD

Fixed Voltage Regulator

Descriptions

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.

Features

• Output Current of 1A

• Short Circuit Current Limit Protection

• Thermal Shutdown Protection
