Variable voltage regulator system
 The present invention relates to a variable voltage regulator that can be easily adjusted via a jumper, or a signal (provided by another circuit) so that the variable voltage regulator can provide at least one of a plurality of discrete voltages to an integrated circuit, such as a microprocessor. This is useful when a replacement microprocessor requires a different operating voltage than the microprocessor it replaced.
