ABSTRACT:
A regulator including a power element between the input terminal and output terminal; and a regulating loop including a differential stage for comparing the output voltage of the regulator with a reference voltage and accordingly driving a gain stage connected to the power element. The output voltage is picked up by the differential stage via a resistive divider, the resistance of which varies according to the value of a logic signal at a control input. When the resistance of the divider changes, the inputs of the differential stage are so unbalanced as to produce an output voltage up or down ramp equal to the slew rate of the regulating loop and proportional to the bias current of the differential stage. Over the up ramp, the shorting protection circuit is turned off for a predetermined time .tau., whereas, over the down ramp, a stage is turned on for absorbing the discharge current of the capacitive load.
