A power controller regulates power from a power source coupled to a power source input to a load coupled to a load output, and this power controller includes a switch and a switching controller. The switch is coupled between the power source input and the load output wherein the switch is switched on and off responsive to an input signal. The switching controller is coupled to the switch wherein the switching controller generates the input signal so that the switch is switched on and off to provide a regulated power output to the load output during active load operations and so that the switch couples the power source to the load output without switching to provide an unregulated power output during stand-by load operations. Related methods and radiotelephones are also discussed. |
