An apparatus comprising a regulator and a control circuit. The regulator may be configured to generate a regulated voltage in response to (i) a reference input signal, (ii) a pull down signal and (iii) a control signal. The control circuit may be configured to generate the control signal in response to a digital complement of the pull down signal. The regulator and the control circuit have a common supply voltage and ground. The regulator may comprise a pass through device and a protection device. The protection device may respond to the control signal to limit a load voltage that passes through the pass through device.
