==Original Abstract Submitted==

A power supply device includes a power supply circuit that permits an output voltage to be supplied to a succeeding-stage circuit, an external terminal configured to be connectable to the succeeding-stage circuit and to a pull-up resistor to which a supply voltage is applied, a transistor having a first terminal connected to the external terminal, a controller that turns the transistor from on to off when, during start-up of the output voltage, the output voltage enters a normal range and a fault detection circuit that can detect at least one of an open fault, in which the external terminal remains open, and a short fault, in which the external terminal is short-circuited to an application terminal for the supply voltage.
