Product Review
LM317 is three-terminal adjustable regulator integrated circuit early made by National Semiconductor and widely used in many integrated circuit manufacturers. Easily use , it just need two external resistance to set output voltage. Besides, its linear adjusting ratio and rejection ratio is better than the standard fixed regulators.
