SLVS059T – JUNE 1976 – REVISED JANUARY 2015 µA78Mxx Positive-Voltage Regulators
1 Features 3 Description This series of fixed-voltage integrated-circuit voltage
regulators is designed for a wide range of
applications. The 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. 1 3-Terminal Regulators
