Abstract
A voltage regulator controls a regulated output voltage (Vout) by feeding it back to a differential input stage () receiving a reference voltage (Vref) and applying an output () to a control electrode of a follower transistor (M) that is coupled to an output stage () which generates the output voltage (Vout). The output stage operates pull-up (MB) and pull-down (MB) transistors in response to a signal (A) produced by the follower transistor (M) during normal regulation operation, and provides fast settling of the output voltage by turning on a transient pull-up transistor (MA) or transient pull-down transistor (MA) in response to the signal (A) produced by the follower transistor (M) during a fast increasing or decreasing transition, respectively, of the load current (I). A filtering resistor (R) is coupled between the output voltage and a common electrode of the transient pull-up and pull down transistors.
