A safety loop voltage regulating circuit includes a power regulation chip (1), and a safety loop (2) and contactor (KM) that are connected with the power regulation chip (1). A plurality of safety switches (S1, S2, ..., S(n)) are arranged in the safety loop (2). A starting end of the safety loop (2) is connected to a power supply terminal (SVCC) of the power regulation chip (1), and a tail end of the safety loop (2) is connected to a grounding end (SGND) of the power regulation chip (1) through the contactor (KM). The power regulation chip (1) further includes a feedback terminal (FB) connected to the tail end of the safety loop (2).
