Abstract
A circuit device generates a signal proportional to the current circulating in an inductor and a current comparator, which is disabled by a stand-by signal, and is input with a feedback signal and with a signal proportional to the current circulating in the inductor and generates a logic comparison signal. A control logic, input with a logic comparison signal and the stand-by signal, drives the switch or the switches of a power stage. A clamp, connected in parallel to a capacitive branch, makes the feedback signal greater than a certain minimum threshold, to make the current that is delivered to the load, when the regulator is not in the stand-by state, greater than a certain minimum current.
