PROBLEM TO BE SOLVED: To optimize the minimum operation voltage of a logic circuit. SOLUTION: A regulator output voltage Vout to be supplied to a logic circuit 19 is controlled based on a voltage V1 corresponding to an operational speed and temperature output from a first resistor/diode circuit 11 and a voltage V2 corresponding to manufacture variation output from a Vt sum circuit 14 and a voltage V3 corresponding to an operational speed and temperature output from a second resistor/diode circuit 15.
