3 Description
This series of fixed-voltage integrated-circuit voltage
regulators is designed for 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
essentially make them 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 can be used as the power-pass element in
precision regulators.
