As shown in figure below,it starts using the maximum output current regulation and control of foot 2 of L200.In this way, C2 would prevent voltage jump of foot2 in starting up, and L200 remains the state ofsmallest output current. As foot5 charges C2 through R2,the output voltage of L200 would gradually increase.According to the component parameters in the graph, it takes 7s for the output voltage to reach the rated value.One also can delay the connection of L200 benchmark end foot 4 and R1 to achieve the purpose of soft start.
