A voltage varying device using a switching element is provided to easily regulate the output characteristic change of an electronic device caused due to voltage, by turning on or off transistors connected in parallel according to the control of a control unit. A voltage varying device using a switching element includes first to N switching elements(Q1~QN) connected in parallel; a control unit(CPU) having first to N ports(CPU P1~CPU PN) connected to on/off terminals of the first to N switching elements, respectively and controlling the output of the first to N ports to turn on or off the first to N switching elements; and a distributing circuit dividing the output voltage generated by the switching elements, at a final output stage of the first to N switching elements and then outputting the divided voltage.
