A switching regulator includes a first switch circuit, a second switch circuit, and a protection circuit. The first switch circuit has a first connection node coupled to a first reference voltage, and a second connection node coupled to one end of an inductor. The second switch circuit has a first connection node coupled to a second reference voltage, and a second connection node coupled to the one end of the inductor. The protection circuit senses a voltage level at the first connection node of the first switch circuit, and selectively enables an auxiliary current path in response to the voltage level at the first connection node of the first switch circuit, wherein the auxiliary current path and at least the first switch circuit are arranged in a parallel connection fashion.
