General Description

These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of

applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and

safe-area compensation. With adequate heatsink they can deliver output currents up to 1.5 ampere.

Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain

adjustable voltages and currents.

This series is offered in 3-pin TO-220, ITO-220 package.

Standard Application

A common ground is required between the input and the

output voltages. The input voltage must remain typically 2.0V

above the output voltage even during the low point on the

Input ripple voltage.

XX = these two digits of the type number indicate voltage.

* = Cin is required if regulator is located an appreciable

distance from power supply filter.

** = Co is not needed for stability; however, it does improve

transient response.
