レギユレータ。[Claims for Utility Model Registration] (1) Current is intermittently passed through the primary winding of a transformer having a plurality of secondary windings by a switching element, and the voltage is boosted and the current is applied to each secondary winding. A multi-output switching leg that stabilizes the plurality of DC outputs by obtaining a plurality of DC outputs using a rectifier and smoothing circuit, detecting the output voltage of one of the output voltages, and controlling the on/off ratio of the switching element. A multi-output switching regulator is characterized in that it controls on/off of a discharge resistor for a smoothing capacitor according to an output voltage other than a detected DC output. (2) The multi-output switch according to claim (1) of the utility model registration, characterized in that when the detected output voltage falls below a predetermined value, a discharge resistor provided at another output is activated. Ngregulator. (3) Utility model registration claim 1, which is characterized in that when the output voltage of the output that controls the switching element's switching element becomes lower than a predetermined value, a discharge resistor of another output is operated. Multi-output switching regulator.
