An integrated circuit comprising a feedback terminal to receive a feedback
signal. A voltage regulator has a feedback input to receive the feedback
signal from the feedback terminal. The voltage regulator has a power
output in communication with an output terminal. The voltage regulator
being responsive to the feedback signal, to generate the power output. A
voltage generator to generate a pull-up voltage having an amplitude
greater than a DC voltage amplitude of the power output. The pull-up
voltage being derived separately from the power output. A pull-up
resistor in communication with the pull-up generator and the feedback
input of the voltage regulator.
