Abstract
A limiting circuit comprises a comparator (B), which makes a comparison between the output voltage (Vc) of a power device and a predetermined reference voltage (Vrif). In the case wherein the output voltage is just below the reference voltage, the comparator supplies a current to the load (L) suitable for preventing the output voltage from falling further below the reference voltage.
