THREE–TERMINAL

POSITIVE FIXED

VOLTAGE REGULATORS

This family of fixed voltage regulators are monolithic integrated circuits

capable of driving loads in excess of 1.0 A. These three–terminal regulators

employ internal current limiting, thermal shutdown, and safe–area

compensation. Devices are available with improved specifications, including

a 2% output voltage tolerance, on A–suffix 5.0, 12 and 15 V device types.

Although designed primarily as a fixed voltage regulator, these devices

can be used with external components to obtain adjustable voltages and

currents. This series of devices can be used with a series–pass transistor to

boost output current capability at the nominal output voltage.

* C is required if regulator is located an

appreciable distance from power supply filter.

** C is not needed for stability; however, it does

improve transient response. If needed, use a

0.1 µF ceramic disc.

* 2% regulators are available in 5, 12 and 15 V devices.
