> As the picture shows, it is a fixed current switch regulator applying circuit which is formed by W723. W723 is a multi-port adjustable positive integrated regulator. Its base voltage is about 7.2 V, which passes through R1 and R2 to add the 3V voltage to the input ports of the same phase. At the same time, the base voltage also passes through R3 and R4 to add the voltage to input ports of the negative phase. When the positive and negative phase input ports are balanced, voltage of R5 is about 1 V.
