As shown in figure is a constant current and voltage-stabilized power supply connected inparallel，featuring high speed, low noise and low impedance. Using LM317 as its constant current source，it can load constant current up to 560mA . Mosfet 2SR3D and luminotron provide low noise reference voltage. As an error amp，LM741 (amp) would compare and amplify the reference voltage and sampling voltage. In order to stabilize the output voltage,the two 3DD15 are used to adjust the output voltage.
