Abstract
Embodiments for at least one method and apparatus of generating a regulated voltage are disclosed. One apparatus includes a voltage regulator. The voltage regulator includes regulator circuitry for generating a regulated voltage from a first power supply and a second power supply, and voltage spike protection circuitry for voltage-spike-protecting the regulator circuitry. The voltage spike protection circuitry includes a charge-storage circuit, and at least one switching element, wherein the at least one switching element comprises a plurality of switching block segments. The charge-storage circuit includes charge-storage circuit segments, and each charge-storage circuit segment is physically closer to at least one of the plurality of switching block segments the charge-storage circuit segment protects, than any other switching block segment.
