An amplifier circuit with an overshoot suppress scheme is provided. The amplifier circuit includes an input amplifier, an output amplifier and a diode device. The output amplifier is coupled to the input amplifier and outputs an output voltage. The diode device is coupled between an output end and an input end of the output amplifier. When a voltage difference between the output end and the input end of the output amplifier is greater than a barrier voltage of the diode device, the diode device is turned on, and an overshoot of the output voltage is reduced.
