The LM317 is a popular adjustable linear voltage regulator. It was invented by Robert C. Dobkin and Robert J. Widlar in 1970 while they worked at National Semiconductor. The LM317 has three pins: Input, output, and adjustment. The device is conceptually an op amp (with a relatively high output current capacity). The inverting input of the amp is the adjustment pin, while the non-inverting input is set by an internal band-gap voltage reference which produces a stable reference voltage of 1.25 V. The Output voltage can be varied in this circuit by varying the resistance of the potentiometer, with this circuit we can make our own bench power supply....
