GENERAL DESCRIPTION
This series of fixed-voltage monolithic 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. In
addition, they can be used with power-pass elements
to make high-current voltage regulators. Each of
these regulators can deliver up to 1.5 A of output
current. The internal limiting and thermal shutdown
features of these regulators make them essentially
immune to overload.
FEATURES
3-Terminal Regulators
Output Current Up to 1.5 A
No External Components
Internal Thermal Overload Protection
High Power Dissipation Capability
Internal Short-Circuit Current Limiting
Output Transistor Safe-Area Compensation

these ratings should not be
exceeded. The built-in
