Because of restrictions by the regulator voltage value, simple series power supply can not adjust the output voltage, while voltage regulation circuit is also not stable enough. In order to solve these two problems, we increase the negative feedback block and employ a constant current source as the load of regulator. Meanwhile, an over current protection section is added to en?sure the safety of the power supply. This power supply is proven to meet the general needs of the present stage.
