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.  \nThese regulators employ internal current limiting safe area protection and thermal shutdown for protection against virtually all overload conditions.  \nLow 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. For applications requiring other voltages, see LM137 datasheet.  \nConnection Diagram  \nFigure 1. TO-220 Package Front View  \nSee Package Number NDE0003B  \nTypical Applications  \n*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.  \n†Required for stability. For value given, capacitor must be solid tantalum. 25μF aluminum electrolytic may be substituted. Values given may be increased without limit.  \nFor output capacitance in excess of 100μF, a high current diode from input to output (1N4001, etc. ) will protect the regulator from momentary input shorts.  \nFigure 2.
