Abstract:
Voltage regulator with extended minimum to maximum current ratio. In some embodiments, a low-dropout (LDO) voltage regulator disposed within a semiconductor package may include an inner loop; and an outer loop coupled to the inner loop, wherein: the inner loop is configured to control a load response of the LDO voltage regulator and to reduce at least one of: a printed circuit board (PCB) effect on the outer loop, a packaging effect on the outer loop, or a parasitic effect on the outer loop; the outer loop is configured to control a voltage at an output of the LDO voltage regulator; the output of the LDO voltage regulator is coupled to an integrated circuit within the semiconductor package; and the PCB, package, and parasitic effects comprise inductive or resistive effects caused by elements disposed outside of the semiconductor package.
