The discloses an LDO circuit with rapid transient response, and belongs to technical field of electronic circuits. The circuit comprises an error amplifier, a first resistor, a second resistor, an output stage and a flip voltage follower, an input end of the output stage is connected with an output end of the error amplifier, and the output end of the output stage is taken as an output end of LDO;the first resistor and the second resistor are in series connection and then is parallel connection with part between the output end of the LDO and the ground, the series connecting point is connected with a positive input end of the error amplifier, and a negative input end of the error amplifier is connected with a reference voltage. According to the LDO circuit, the flip voltage follower is connected between the output end of the error amplifier and the output stage of the LDO, a folding type cascade structure is adopted, and a large current can be rapidly provided for loads by the LDO byinserting in a super source stage follower in the flip voltage follower, in some embodiment, a positive voltage detecting module is arranged at the output end of the LDO circuit to detect the overshoot of an LDO output voltage, and a large drop-down voltage is given to maintain the stability of the output voltage. According to the LDO circuit, the output voltage is stable and has stronger loadingcapability.
