Description

The SI79XX series of fixed-voltage monolithic intergrated-

circuit voltage regulators designed to complement Series

SI78XX in a wide range of applications. These applications

include on-card regulation for elimination of noise and

distribution problems associated with single-point regulation.

Each of these regulators can deliver up to 1A of output

current. The internal current limiting and thermal shutdown

features of these regulators make them essentially immune

to overload. In addition to use as fixed-voltage regulators,

thesedevices can be used with external components to

obtain adjustable output voltage and current and also as the

power pass element in precision regulators.

Features
