。[Claims for Utility Model Registration] (1) A switching element and an inductor are connected in series between a DC input power source and a load, and the switching element turns on and off the current flowing through the inductor to supply a constant voltage to the load. In the chopper type switching regulator, a switch element is provided between the output of the chopper type switching regulator and the load, and the switch element is turned on and off according to the output voltage of the chopper type switching regulator. This is a switching regulator that is characterized by: (2) The stopper type switching regulator according to claim (1) of the utility model registration, characterized in that the stopper type switching regulator is a step-down type. (3) Utility model registration claim No. 1, which is characterized in that when the output voltage of the stopper type switching regulator exceeds a predetermined value, the switching element is turned off and the power supply to the load is turned off. 2.) Chotsper type switching regulator described in item ). (4) A utility model registration application characterized in that the output voltage of a switching element is detected, compared with a reference voltage, and the on/off ratio of the switching element is controlled according to the result to supply a constant voltage to a load. Range number (1)
Chotsupah type switching regulator described in section.
