Abstract
A voltage regulating circuit is provided for regulating an output voltage in order to minimize an absolute difference between a level of said output voltage and a reference level. The voltage regulating circuit comprises a voltage regulator and a reference level generator. The reference level generator generates an internal reference level on the basis of said output voltage level and said reference level such that said internal reference level does not exceed said output voltage level by more than a maximum allowed increment. The voltage regulator regulates said output voltage in order to minimize an absolute difference between said output voltage level and said internal reference level. A method of regulating an output voltage is also disclosed.
