LM317 is a common adjustable Integrated voltage regulator. The max output current is 2.2A, output votage 1.25～37V. The connection is shown as below: Between 1 and 2 feet is 1.25V voltage reference. For making sure the output performance of the regulator, R1 should be less than 240 Ohm. Changing R2 can adjust the voltage of regulator. D1 and D2 are usd for protecting LM317.
