DESCRIPTION

The LM79XX series of 3-terminal regulators is

available with fixed output voltages of −5V, −12V, and

−15V. These devices need only one external

component—a compensation capacitor at the output.

The LM79XX series is packaged in the TO-220 power

package and is capable of supplying 1.5A of output

current.

These regulators employ internal current limiting safe

area protection and thermal shutdown for protection

against virtually all overload conditions.

Low ground pin current of the LM79XX series allows

output voltage to be easily boosted above the preset

value with a resistor divider. The low quiescent

current drain of these devices with a specified

maximum change with line and load ensures good

regulation in the voltage boosted mode.

For applications requiring other voltages, see LM137

datasheet.
