Abstract
A power supply voltage controlling circuit has a voltage regulator circuit that supplies a current to an output terminal from at least any of a first power supply and a second power supply, and compares an output voltage at the output terminal with a first reference voltage to adjust the output voltage to approach the first reference voltage; and a controller circuit that supplies the first reference voltage to the voltage regulator circuit and controls the voltage regulator circuit by outputting, to the voltage regulator circuit, at least any of a first enable signal for enabling the first power supply to supply a current to the output terminal and a second enable signal for enabling the second power supply to supply a current to the output terminal.
