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.
