Product Summary
General Description:The LM79XX series of 3-terminal regulators is available with fixed output voltages of b5V, b8V, b12V, and b15V.
These devices need only one external componentDa 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.These regulators employ internal current limiting safe area protection and thermal shutdown for protection against vir-
tually 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 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 data 
sheet。
