1. A current controlled voltage regulator for regulating a voltage at a load, comprising:

  • a connector to connect to a power source;

    at least one resistive element coupled in series between the power source and the load;

    a control circuit coupled across the at least one resistive element to receive first and second signals indicative of a drive level of the voltage regulator and to provide a control signal in response to a difference between the first and second signals; and

    a conduction device coupled across the load and coupled to the control circuit to receive the control signal and to decrease conduction if the difference increases and increase conduction if the difference decreases, wherein the change in conduction is substantially proportional to the difference between the first and second signals, and wherein a substantially constant voltage is maintained across the load.
