LM79XX Series

3-Terminal Negative Regulators

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.

General 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 ca-

pacitor at the output. The LM79XX series is packaged in the

TO-220 power package and is capable of supplying 1.5A of

output current.

For applications requiring other voltages, see LM137

datasheet.

Features

n Thermal, short circuit and safe area protection

n High ripple rejection

These regulators employ internal current limiting safe area

protection and thermal shutdown for protection against vir-

tually all overload conditions.

n 1.5A output current

n 4% tolerance on preset output voltage

Low ground pin current of the LM79XX series allows output

voltage to be easily boosted above the preset value with a

Required if regulator is separated from filter capacitor by

more than 3". For value given, capacitor must be solid

tantalum. 25µF aluminum electrolytic may be substituted.

†

Required for stability. For value given, capacitor must be

solid tantalum. 25µF aluminum electrolytic may be substi-

tuted. Values given may be increased without limit.

For output capacitance in excess of 100µF, a high current

diode from input to output (1N4001, etc.) will protect the

regulator from momentary input shorts.
