Positive Voltage Regulators
GENERAL 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 1.5A 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 whit external components to obtain
adjustable output voltages and currents, and also can be used as the power-pass element in
precision regulators.
Compliance to RoHS.
