Original Abstract Submitted

A power supply circuit includes an amplifier and first and second transistors. The amplifier is configured to provide a drive potential at its output. The first transistor is coupled between a voltage supply terminal and an output terminal, and has a first control terminal coupled to the amplifier output, and is configured to receive at least a portion of the drive potential at the first control terminal. The second transistor is coupled between the first control terminal and the output terminal, and has a second control terminal coupled to the amplifier output. A threshold voltage of the first transistor is lower than a threshold voltage of the second transistor. The second transistor can operate to adaptively reduce the portion of the drive potential at the first control terminal, for example, by the second transistor turning on responsive to a voltage at the output terminal being lower than a voltage level.
