LM79XX Series 3-Terminal Negative Regulators  
General Description  
The LM79XX series of 3-terminal regulators is available with  
these devices with a specified maximum change with line  
and load ensures good regulation in the voltage boosted  
mode.

12V, and 15V.  
fixed output voltages of  
5V,  
8V,  
These devices need only one external componentÐa com-  
pensation 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.  
For applications requiring other voltages, see LM137 data  
sheet.  
These regulators employ internal current limiting safe area  
protection and thermal shutdown for protection against vir-  
tually all overload conditions.

voltage to be easily boosted above the preset value with a  
resistor divider. The low quiescent current drain of

Required for stability. For value given, capacitor must be  
solid tantalum. 25 mF aluminum electrolytic may be substi-  
tuted. Values given may be increased without limit.  
For output capacitance in excess of 100 mF, a high current  
diode from input to output (1N4001, etc.) will protect the  
regulator from momentary input shorts.
