ABSTRACT:
A device includes an N-channel transistor for output, a voltage raising circuit, a voltage dropping circuit, and an amplifier. A power supply voltage that is a first voltage is supplied to one end of the output N-channel transistor, and the other end of the output N-channel transistor functions as an output terminal. The voltage raising circuit raises the first voltage to generate a second voltage higher than the first voltage. The voltage dropping circuit reduces the second voltage to generate a third voltage that is higher than the first voltage and is lower than the second voltage. The amplifier amplifies the difference between a reference voltage and a voltage generated at the output terminal, using the third voltage as a power supply voltage, to generate a fourth voltage, and supplies the fourth voltage to the gate of the N-channel transistor for output.
