Abstract
An integrated circuit including at least one low-dropout voltage regulator (LDO) capable of delivering a regulated output voltage using a reference voltage (VREF), comprises means for generating a substitution voltage (VRMP) in the form of a ramp and control means capable of replacing the reference voltage (VREF) by the substitution voltage as long as the substitution voltage (VRMP) is lower than the reference voltage (VREF).
