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.

junction temperature, these ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal
resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.
