PROBLEM TO BE SOLVED: To reduce leak current of a voltage supply circuit using a MOS transistor at the time of standby. SOLUTION: The voltage supply circuit consists of a n-channel MOS transistor TR11 with low threshold voltage in which a drain is connected to the power source side and a p-channel MOS transistor TR12 in which a source is connected to a source of the n-channel MOS transistor TR11 and which supplies voltage vii from the drain to a load circuit. At the time of standby, since voltage Vge=1V is impressed between a gate and the source of the p-channel MOS transistor TR12, the p-channel MOS transistor operates in a cutoff area deeper than usual.
