Patent ID: 8471541

Claim:
A semiconductor device packed in one package, the semiconductor device being for a regulator and for use with a capacitor, the semiconductor device comprising: an input voltage terminal; an output terminal; a ground potential terminal; a power terminal; a first terminal, the first terminal being to be coupled to the output terminal via the capacitor; a first MOSFET having a source-drain path coupled between the input voltage terminal and the output terminal and a gate; a second MOSFET having a source-drain path coupled between the output terminal and the ground potential terminal and a gate; a control circuit coupled to the power terminal, coupled to provide a first control signal to the gate of the first MOSFET and coupled to provide a second control signal to the gate of the second MOSFET; and a P-channel switch MOSFET having a source-drain path coupled between the power terminal and the first terminal, a source thereof being coupled to a back gate thereof and to the first terminal, and a drain thereof being coupled to the power terminal.
