0 ~ ± 30V, 1.5A power supply circuit diagram composed of LM317 is shown as the chart. The features of the power supply can be seen from the figure, its positive and negative output voltage can be transferred to the minimum 0V. LM317 (LM337) can only be transferred to the 1.25 (-1.25) V under normal circumstances, but the adjustment end of the adjustable three-terminal is added the appropriate amount of reverse bias, the output voltage can be changed to zero by negative voltage of TH2 emitter being connected to VR1, and the positive voltage of TH1 emitter being connected to VR2.
