The present invention discloses a current regulation module for providing a predetermined current. The current regulation module comprises a linear power conversion circuit, a switching power conversion circuit, a current detector, and a controller. The current detector is used to detect the output current of the current regulation module and output a detected current value. The controller control the switches in the linear power conversion circuit and the switching power conversion circuit in accordance with the detected current value, to strengthen the dynamic response ability to the sudden change in the output current.
