This family of fixed voltage regulators are monolithic integrated circuits

capable of driving loads in excess of 3.0 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 AC–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

supply up to 15 A at the nominal output voltage.

XX Indicates nominal voltage.

A common ground is required between the input and the output voltages. The input voltage must

remain typically 2.2 V above the output voltage even during the low point on the input ripple voltage.

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

XX these two digits of the type number indicate voltage.

# Automotive temperature range selections are avail-

able with special test conditions and additional

tests. Contact your local Motorola sales office for

information.

** C is required if regulator is located an appreciable distance from power supply filter.

** (See Applications Information for details.)

** C is not needed for stability; however, it does improve transient response.
