FEATURES

DESCRIPTION

The LM79LXXAC series of 3-terminal negative

•

Preset Output Voltage Error is Less than ±5%

Over Load, Line and Temperature

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, when combined with a minimum

output 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.

The LM79LXXAC series also includes, as self-

output transistor power dissipation limiting,

temperature independent 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 TO package, the 8-lead SOIC

package, and the 6-Bump DSBGA package.

See AN-1112 (SNVA009) for DSBGA

Considerations

For output voltages other than the pre-set -5V, -12V

and -15V, the LM137L series provides an adjustable

output voltage range from -1.2V to -47V.

Typical Applications

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

A 1μF aluminum electrolytic may be substituted.

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

substituted.

−V₀= −5V − (5V/R1 + I_Q) • R2,

5V/R1 > 3 I_Q
