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-point regulation. Each of these regulators can deliver up to 500 mA 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 as the power-pass element in precision regulators.
