Zusammenfassung:	PURPOSE:To alleviate the loss of a second output stabilizing Zener diode by connecting the Zener diode between a second output and a first output. CONSTITUTION:A switching power source is composed of a transformer T, a switching transistor (Tr) 4, output rectifying diodes 5, 6, and smoothing circuits 7, 8, the Tr 4 is driven to generate an induced voltage in a secondary winding 2, which is positively fed back from a feedback winding 3, and the output is driven to be stabilized to obtain output voltages V01, V02. In this case, the stabilizing Zener diode 9' of the output V02 is connected between the output V02 and the output V01. Thus, the voltage value of the diode 9' becomes V02-V01 with respect to the conventional value V02, thereby alleviating the loss of the diode 9'.
