Abstract
Generally, with low drop out (LDO) regulators that use multiplexed power supplies, the transistors within the regulator can use a substantial amount of area. Here, a regulator is provided that uses a multiplexer to commonly control the back-gates of multiple power transistors within the LDO. By doing this, the area overhead that would normally be present with these switches (of the multiplexer) can be dramatically reduced without sacrificing performance.
