description/ordering information
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-pointregulation. 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 elementin precision
regulators.
