The LM79XX series of 3-terminal regulators is available withfixed output voltages of b5V, b8V, b12V, and b15V.These devices need only one external componentÐa com-pensaTIon capacitor at the output. The LM79XX series ispackaged in the TO-220 power package and is capable ofsupplying 1.5A of output current.These regulators employ internal current limiTIng safe areaprotecTIon and thermal shutdown for protecTIon against vir-tually all overload conditions.Low ground pin current of the LM79XX series allows outputvoltage to be easily boosted above the preset value with aresistor divider. The low quiescent current drain ofthese devices with a specified maximum change with lineand load ensures good regulation in the voltage boostedmode.For applications requiring other voltages, see LM137 datasheet.FeaturesY Thermal, short circuit and safe area protectionY High ripple rejectionY 1.5A output currentY 4% tolerance on preset output voltage
