Abstract
A voltage regulator package includes a voltage regulator module that outputs a voltage signal of a particular voltage level through an output terminal is provided. The voltage regulator module may be switched on according to a periodic signal having a periodic signal frequency as a variable. The periodic signal frequency may be tuned to reduce impedance, jitter, or noise.
