Adjustable voltage and current power supply LM337 LM317
LM317 (positive voltage regulator) and LM337 (negative voltage regulator) output series-connected power transistors powered by the 5k and 20k potentiometer binary (stereo) type if you use the + and – output of the current and voltage settings set equal can Show some circuits and found that the output resistance of between 200 ~ 240 I…
