Abstract

A power supply voltage regulating apparatus includes: a reference voltage generating circuit that generates a reference voltage; an operational amplifier that amplifies the reference voltage and outputs the amplified reference voltage as a power supply voltage; a switching circuit that is connected between an output terminal of the operational amplifier and ground, and that performs a switching operation; a ring oscillator that is connected in parallel with the switching circuit between the output terminal of the operational amplifier and ground, and that generates an oscillation signal; and a controller that is connected with an input terminal of the reference voltage generating circuit, and that controls the reference voltage in accordance with an oscillating frequency of the oscillation signal, a temperature of the switching circuit, and an operating frequency of the switching circuit, to regulate the power supply voltage that is output from the operational amplifier.
