A low dropout linear regulator, a starting method, an electronic device, and a chip are provided. Wherein the low dropout linear regulator comprises an error amplifier circuit, an over current circuit and an over-current adjustor, the starting method includes: beginning a soft-starting process of the low dropout linear regulator and turning on a first transistor and a second transistor to provide a over current to raise an output voltage of the low dropout linear regulator; maintaining the 'turn on' state of the first transistor and the second transistor and decreasing the over current according to a signal obtained from the error amplifier circuit after the output voltage of the low dropout linear regulator reaches a starting voltage of the error amplifier circuit; wherein the error amplifier circuit begins to operate when the output voltage of the low dropout linear regulator reaches the starting voltage of the error amplifier circuit.
