Abstract
A voltage regulator having a regulator output operating at a predetermined output voltage level is disclosed. The voltage regulator includes a switching regulator that has a first regulated output providing a first output voltage level, where the first output voltage level is approximately equal to the predetermined output voltage. The first regulated output is coupled to the regulator output. The voltage regulator includes a linear regulator that has a second regulated output providing a second output voltage level, where the second output voltage level is less than the first output voltage level. The second regulated output is coupled to the first regulated output such that the voltage at the regulator output is maintained at approximately the predetermined output voltage level by operation of the switching regulator until the regulator output falls below the second output voltage level at which time the regulator output is maintained at approximately the predetermined output voltage level by operation of either the linear regulator or both the linear regulator and the switching regulator.
