A power down circuit that provides an on-state electrical current to a load circuit that does not depend significantly on power control signal logic levels and that provides a widened off-state control signal voltage range. A power down circuit according to the present teachings includes a switching transistor for providing an electrical current to a load circuit in an on-state and for interrupting the electrical current in an off-state and that includes a circuit for operating the switching transistor in a triode region during the on-state.
