Abstract
Upon sending out a first power-supply voltage having a first value to first and second power supply lines in a first mode and sending out a second power-supply voltage having a second value lower than the first value to the second power supply line in a second mode, when switching a power-supply device from the first mode to the second mode, the value of the first power-supply voltage generated in a first power-supply circuit is changed to the second value first, the first and second power supply lines are temporarily connected together and then cut off from each other, and then the generating operation of the first power-supply voltage is stopped.
