LM320L/LM79LXXAC Series

3-Terminal Negative Regulators

TO-92 package, 8-lead SOIC package, and the 6-Bump

micro SMD package. The LM320L series is available in the

3-lead TO-92 package.

General Description

The LM320L/LM79LXXAC dual marked series of 3-terminal

negative voltage regulators features fixed output voltages of

−5V, −12V, and −15V with output current capabilities in

excess of 100mA. These devices were designed using the

latest computer techniques for optimizing the packaged IC

thermal/electrical performance. The LM79LXXAC series,

even when combined with a minimum output compensation

capacitor of 0.1µF, exhibits an excellent transient response,

a maximum line regulation of 0.07% V_O/V, and a maximum

load regulation of 0.01% V_O/mA.

For output voltage other than −5V, −12V and −15V, the

LM137L series provides an output voltage range from 1.2V

to 47V.

Features

n Preset output voltage error is less than 5% overload,

line and temperature

n Specified at an output current of 100mA

n Easily compensated with a small 0.1µF output

capacitor

n Internal short-circuit, thermal and safe operating area

protection

n Easily adjustable to higher output voltages

n Maximum line regulation less than 0.07% V_OUT/V

n Maximum load regulation less than 0.01% V_OUT/mA

n See AN-1112 for micro SMD considerations

The LM320L/LM79LXXAC series also includes, as self-

protection circuitry: safe operating area circuitry for output

transistor power dissipation limiting, a temperature indepen-

dent short circuit current limit for peak output current limiting,

and a thermal shutdown circuit to prevent excessive junction

temperature. Although designed primarily as fixed voltage

regulators, these devices may be combined with simple

external circuitry for boosted and/or adjustable voltages and

currents. The LM79LXXAC series is available in the 3-lead

Typical Applications

Adjustable Output Regulator

Fixed Output Regulator

*Required if the regulator is located far from the power supply filter. A 1µF

aluminum electrolytic may be substituted.

00774803

−V = −5V − (5V/R1 + I ) • R2,

5V/R1 3 I

**Required for stability. A 1µF aluminum electrolytic may be substituted.
