Claim:
1. A semiconductor integrated circuit device comprising: a first voltage terminal supplied with a first voltage; an output terminal; a first MOSFET having a first input electrode, a drain, a source, and a second input electrode located closer to the drain than the first input electrode, the first MOSFET being connected between the first voltage terminal and the output terminal and electrically connecting the first voltage terminal to the output terminal according to a first input signal supplied to the first input electrode; a drive circuit connected to first input electrode of the first MOSFET, the drive circuit generating the first input signal so that the first MOSFET is switched on and off; and a first voltage generating circuit connected to the second input electrode of the first MOSFET, the first voltage generating circuit supplying a negative voltage negative in polarity relative to a voltage at the source of the first MOSFET, to the second input electrode.
