C1 should be fitted close to the converter pins. 2. The external capacitor C1 must be added on the input, to prevent voltage transients caused by damage to the 3. 4. 5. module. The regulator proposed to establish the input voltage by soft start. If the input voltage changes from low voltage to high voltage abruptly, the regulator might be damaged. Not usable for plug and play applications. Do not use more regulators in parallel operation.
