ABSTRACT:
To solve the problem of the conventional reference voltage generation circuit in that an output voltage exceeds a predetermined voltage value, there is provided a reference voltage generation circuit including: a voltage generation circuit provided between a first power supply and a second power supply, to output an output voltage to an output terminal; an auxiliary start-up circuit provided between the output terminal and the first power supply, to supply a voltage of the first power supply to the output terminal; and a control circuit that switches the auxiliary start-up circuit between an operating state and a non-operating state according to a value of a voltage at the output terminal.
