Abstract
A constant voltage circuit comprises a capacitor connected between one end of a MOS transistor controlled by an operation-stop control signal and an output terminal of an inverter for inverting the operation-stop control signal. When, in the circuit having this arrangement, the transistor for operation-stop control is turned off and the hold mode is ended, the potential at one end of the transistor is quickly lowered to the ground potential. The result is to quicken the start of operation of the constant voltage circuit and hence the rise of the constant voltage output.
