1. A voltage regulator for generating an output voltage comprising:

  • (a) an amplifier having an amplifier output;

    (b) a pass device having a first node which is coupled to the amplifier output, the pass device generating the output voltage via a second node of the pass device; and

    (c) a voltage control circuit which applies a voltage to the first node of the pass device to accelerate the response time of the amplifier in enabling the voltage regulator to reach its final regulated output voltage.
