Abstract
A power supply device includes a switching circuit and first and second control circuits. The switching circuit is between a regulator circuit and a terminal and is configured to transition between a first state in which a second power supply voltage is supplied to the terminal and a second state in which supply of the second power supply voltage to the terminal is cut off. The first control circuit is configured to output a reset signal that is set to a first voltage or a second voltage. The second control circuit is configured to be driven by the second power supply voltage and to perform control so that the switching circuit transitions to the first or second state when the reset signal is at the first voltage. The switching circuit is configured to switch to the second state when the reset signal is set to the second voltage.
