ABSTRACT:
A voltage regulator has a device for regulating an output voltage, having an input to receive an input voltage and an output to deliver an output voltage of a constant level, and a device for correcting a drop-out voltage violation, coupled to the device for regulating, to determine an occurrence of a drop-out voltage violation and to cause the device for regulating to change the level of the output voltage upon detection of the drop-out voltage violation. A method for regulating an output voltage has the steps of receiving an input voltage, generating and outputting a regulated output voltage of a constant level, monitoring occurrence of a drop-out voltage violation, and causing a change of the level of the output voltage upon detection of the drop-out voltage violation.
