A technique for controlling a power supply with power supply control element with a tap element. In one embodiment, a power supply regulator includes a power transistor having first, second, third and fourth terminals. A control circuit is included, which is coupled to the third and fourth terminals of the power transistor. The power transistor is configured to switch a current between the first and second terminals in response a control signal received from the control circuit at the third terminal. A voltage between the fourth and second terminals of the power transistor is substantially proportional to a current flowing between the first and second terminals when a voltage between the first and second terminals is less than a pinch off voltage. The voltage between the fourth and second terminals of the power transistor is substantially constant and less than the voltage between the first and second terminals when the voltage between the first and second terminals is greater than the pinch off voltage.
