Abstract

A semiconductor device, has a main transistor that is a first-conductivity-type MOS transistor and has the drain connected to a first potential; a first switch circuit that is connected between the source of said main transistor and a second potential; a dummy transistor that is a first-conductivity-type MOS transistor whose source serves also as the source of said main transistor; and a second switch circuit that is connected between the drain of said dummy transistor and said first potential or said second potential.
