description
This series of fixed-negative-voltage monolithic
integrated-circuit voltage regulators is designed
to complement Series µA7800 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 1.5 A 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, these
devices can be used with external components to
obtain adjustable output voltages and currents
and also as the power pass element in precision
regulators.
