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% VO/V, and a maximum  
load regulation of 0.01% VO/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% VOUT/V  
n Maximum load regulation less than 0.01% VOUT/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
