Claim 4:
5. The output circuit according to claim 4,
wherein the first current source is connected between the back gate of the first PMOS transistor switch and a positive power supply voltage terminal that receives a positive power supply voltage,
wherein the first back gate control switch is connected between the back gate of the first PMOS transistor switch and a reference power supply voltage terminal that receives the reference power supply voltage,
wherein the first load element is composed of an MOS transistor having a diode connection configuration connected between the source or the drain of the first PMOS transistor switch and the back gate of the first PMOS transistor switch, or
a PMOS source follower transistor in which a gate receives the voltage of the source or the drain of the first PMOS transistor switch as the first voltage and a source is connected to the back gate of the first PMOS transistor switch.
