SI79XXA
Elektronische Bauelemente
3-Terminal
Negative
Voltage Regulator
Description
The SI79XXA series of fixed-voltage monolithic intergrated-
circuit voltage regulators designed to complement Series
SI78XXA 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 1.5A 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.
