The regulator proposed to establish the input voltage by soft-start, no plug and play, if the input voltage changes from low voltage to high voltage abruptly, the regulator might be damaged. 1. The input current amount of the back-grade regulator and the pre-class load should be less than or equal the max load current of the pre-class regulator. 2. If the applications is high-voltage input, the regulator must add an external capacitor C1(≤47μF/100V) to prevent voltage spikes caused by damage to the module. 2. If further filtering is required, please add components as per the above circuit (We recommend not to add components), if request, please make sure the capacitors C1 ≤47μF, C2≤10μF more close to the back-grade regulator. 3. No parallel connection.
