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 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 element in precision

regulators.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
