Abstract
A voltage regulator includes a regulator output and an output capacitor and a variable-conductivity device in series connection between the regulator output and a voltage reference. The variable-conductivity device is configured to have an initial conductivity. A current then is provided at the regulator output in response to a power-on event. A conductivity of the variable-conductivity device is gradually increased from the initial conductivity in response to the current at the regulator output. In another implementation, a voltage regulator includes a regulator output coupled to a voltage rail to provide a current. The voltage regulator includes a capacitive circuit including an output capacitor and a variable-conductivity device coupled in series between the regulator output and a voltage reference. The voltage regulator includes an adjustment circuit configured to gradually increase a conductivity of the variable-conductivity device in response to an application of the current at the regulator output.
