DESCRIPTION  
Figure 1. TO-220 Package  
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 capacitor at the output.  
The LM79XX series is packaged in the TO-220 power  
package and is capable of supplying 1.5A of output  
current.  
Front View  
See Package Number NDE0003B  
Typical Applications  
These regulators employ internal current limiting safe  
area protection and thermal shutdown for protection  
against virtually all overload conditions.  
Low ground pin current of the LM79XX series allows  
output voltage to be easily boosted above the preset  
value with a 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.  
*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.  
For applications requiring other voltages, see LM137  
datasheet.  
†Required for stability. For value given,  
capacitor must be solid tantalum. 25μF  
aluminum electrolytic may be substituted.  
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.
