1. A voltage regulator, comprising:

  • a pass element having a control input coupled to a control node and operable to generate an output voltage at an output node;

    a negative feedback amplifier operable to receive a reference voltage and the output voltage and generate a signal at the control node based on a difference between the reference voltage and the output voltage; and

    a noise cancellation circuit coupled to the control node and the output node and operable to generate a bias current at the control node based on the output voltage.
