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
