Patent ID: 7898234

Claim:
In a voltage regulator comprising a regulator output and comprising an output capacitor and a variable-conductivity device in series connection between the regulator output and a voltage reference, a method comprising: configuring the variable-conductivity device to have an initial conductivity; providing a current at the regulator output in response to a power-on event; detecting, at an adjustment circuit, an initial application of a current at the regulator output; gradually increasing a conductivity of the variable-conductivity device from the initial conductivity at a predetermined rate that is compatible with a loop response of the voltage regulator, wherein the predetermined rate is set by the adjustment circuit in response to the initial application of the current at the regulator output; providing a feedback signal to a voltage dependent current source based on a difference between an output voltage and a desired voltage; and varying the current at the regulator output based on the feedback signal received at the voltage dependent current source.
