Abstract: Described is an apparatus which comprises: a first power supply node to supply input power supply; a power transistor coupled to the first power supply node; a multiplexer to selectively control gate terminal of the power transistor according to whether the power transistor is to operate as part of a low dropout voltage regulator (LDO-VR) or is to operate as a digital switch; and a second power supply node coupled to the power transistor, the second power supply node to provide power supply to a load from the power transistor.
