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% VO/V, and a maximum load regulation of  
0.01% VO/mA.

output transistor power dissipation limiting,  
a
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 + IQ) • R2,  
5V/R1 > 3 IQ
