Original Abstract Submitted
An integrated circuit includes a first transistor coupled between a power input and a power output, the first transistor being an N-type transistor and having a first transistor control input; a first amplifier stage having a reference input, a feedback input, and a first amplifier output, the feedback input coupled to the power output; a second amplifier stage having an amplifier input and a second amplifier output, the amplifier input coupled to the first amplifier output, and the second amplifier output coupled to the first transistor control input; and a first biasing circuit coupled to the first transistor control input, the first biasing circuit having an electrical control input coupled to the power output.
