1. A voltage regulator, comprising:

  • regulator circuitry generating a regulated voltage from a first power supply and a second power supply;

    voltage spike protection circuitry for voltage-spike-protecting the regulator circuitry, comprising a charge-storage circuit;

    at least one switching element, wherein the at least one switching element comprises a plurality of switching block segments, wherein the plurality of switching block segments of the at least one switching element are electrically connected in parallel;

    whereinthe charge-storage circuit comprises 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.
