Various embodiments, disclosed herein, include apparatus and methods to provide separate regulated voltages to an electronic device. Multiple voltage regulators can be provided with phase alignment circuitry coupled to the multiple voltage regulators. The multiple voltage regulators can be structured with each voltage regulator having an output separate from the output of the other voltage regulators. The phase alignment circuitry can provide for relative phases among voltage regulator ripples at the output pins of the multiple voltage regulators to be maintained at a certain relationship. Additional apparatus, systems, and methods are disclosed.
