description An embodiment of the present disclosure provides a power noise suppression circuit for machine equipment, which dynamically obtains a noise component in an input voltage provided by the power supply, generates a noise voltage accordingly, and compares the noise voltage with a feedback voltage to obtain a stable and low-noise power voltage, wherein the feedback voltage is generated by the power noise suppression circuit according to the power voltage. Therefore, the power noise suppression circuit of the embodiment of the present disclosure is particularly suitable for use in the machine equipment which is needed to be monitored and/or controlled precisely, such as a precision machining equipment or a semiconductor manufacturing equipment.
