TO-220 Package The LM79XX series of 3-terminal regulators is Front View available with fixed output voltages of −5V, −12V, and See Package Number NDE0003B −15V. These devices need only one external component—a compensation capacitor at the output. The LM79XX series is packaged in the TO-220 power Typical Applications package and is capable of supplying 1.5A of output current. 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 *Required if regulator is separated from current drain of these devices with a specified filter capacitor by more than 3 ″. For value maximum change with line and load ensures good given, capacitor must be solid tantalum. regulation in the voltage boosted mode. 25 μF aluminum electrolytic may be substituted. For applications requiring other voltages, see LM137 †Required for stability. For value given, datasheet. capacitor must be solid tantalum. 25 μF aluminum electrolytic may be substituted. Values given may be increased without limit. For output capacitance in excess of 100 μF, a high current diode from input to output (1N4001, etc.) will protect the regulator from momentary input shorts. Figure 2.
