A disk drive system includes a fixed output voltage regulator including an output terminal that provides a substantially fixed output voltage. A pluralities of loads are connected in parallel. A resistor is connected in series between the output terminal of the voltage regulator and the plurality of loads. The resistor causes a voltage provided to the plurality of loads to sag, as compared to the substantially fixed output voltage, when current is pulled, by one or more of the loads, through the resistor.
