3-Terminal Negative Regulators  
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.  
General Description  
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 ca-  
pacitor 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  
datasheet.  
Features  
n Thermal, short circuit and safe area protection  
n High ripple rejection  
These regulators employ internal current limiting safe area  
protection and thermal shutdown for protection against vir-  
tually all overload conditions.  
n 1.5A output current  
n 4% tolerance on preset output voltage  
Low ground pin current of the LM79XX series allows output  
voltage to be easily boosted above the preset value with a

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.

Required for stability. For value given, capacitor must be  
solid tantalum. 25µF aluminum electrolytic may be substi-  
tuted. 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.
