Abstract:
1. A voltage regulation circuit having an input terminal for receiving a supply voltage and having an output terminal, comprising: an amplifier that receives the supply voltage and produces a regulated output voltage at the output terminal wherein said amplifier responds to a change to the regulated output voltage only after an amplifier response delay time; a feedback circuit operatively connected to the output terminal and to a feedback terminal of said amplifier; a decoupling capacitor operatively connected to the output terminal arranged to provide a decoupling capacitor current to the output terminal only during the amplifier response delay time; and a supplemental current source operatively connected to the output terminal, said supplemental current source controllably providing a supplemental current to the output terminal in co-operation with the decoupling capacitor providing the decoupling capacitor current only during the amplifier response delay time thereby stabilizing the regulated output voltage by substantially eliminating a downward going voltage transition at the output terminal during the amplifier response delay time.
