A method and circuit for suppressing a bias current and decreasing power consumption. A current suppression circuit is coupled to a circuit element, which is capable of conducting the bias current. Coupling the current suppression circuit to the circuit element forms a node. In one operating mode, the current suppression circuit applies a voltage to the node in response to a heavy load. In another operating mode, the current suppression circuit lowers the voltage at the node in response to a light load or no load. Lowering the voltage at the node decreases the flow of bias current through the circuit element thereby lowering power loss.
