Title: Stabilized direct-current power supply device

Abstract: In a conventional stabilized direct-current power supply device with a soft starting function, soft starting is achieved by exploiting the rise in a reference voltage. Thus, soft starting is impossible when the reference voltage has already risen. A stabilized direct-current power supply device of the invention has a current suppression circuit that, when the output voltage rises, suppresses the current output from a voltage conversion circuit that converts the input voltage into the output voltage to be fed out. Thus, soft starting is possible even when the reference voltage has already risen.
