Abstract
A semiconductor integrated circuit device for controlling an external output transistor is provided. The semiconductor integrated circuit device comprises: a first power supply circuit including an output circuit and providing a first series regulator in cooperation with the output external transistor; and a plurality of terminals. The plurality of terminals includes a control signal output terminal and high and low electric potential side power supply terminals for supplying electric power to the first power supply circuit. At least one of the high and low electric potential side power supply terminals is arranged adjacent to the control signal output terminal and defined as a first terminal. Short-circuiting between the control signal output terminal and the first terminal causes the external output transistor to switch into an off state.
