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, wherein the voltage spike protection circuitry includes a dissipative element and a charge-storage circuit. One method includes a method of generating a regulated voltage. The method includes regulator circuitry generating a regulated voltage from an input voltage, and voltage-spike-protecting the regulator circuitry with voltage spike protection circuitry, wherein the voltage spike protection circuitry includes a dissipative element and a charge-storage circuit.
