Abstract
A switching transistor has its drain and source respectively connected to a gate and a source of an output transistor for supplying output current to a load, and its gate connected to an internal grounding wire GW to be connected to a grounding terminal GND. A resistance element Rconnects the gate to the source of the switching transistor. When a voltage not smaller than a predetermined value is generated across the resistance element Rat turn-on, due to a parasitic capacitance existing between a power supply terminal. Vcc and the internal grounding wire GW, the switching transistor can be turned on to turn off the output transistor.
