[Claims for Utility Model Registration] (1) An amplifier using two power supplies, a Zener diode that turns on when the output of the amplifier reaches the Zener voltage when the power is turned on, and a voltage divider that divides the output of the amplifier. In a constant voltage circuit comprising a piezoresistor, the Zener voltage is applied to one input terminal serving as a reference of the amplifier, and the voltage divided by the voltage dividing resistor is fed back to the other input terminal of the amplifier, A constant voltage circuit characterized in that an initial setting means is provided for applying a voltage until the Zener voltage is reached to the one input terminal through a switching element when the power is turned on. (2) Utility model registration claim 1, characterized in that the initial setting means is configured to output via a voltage dividing circuit that divides the power supply voltage and a diode that performs switching control of the core voltage. The constant voltage circuit described.
