The output load should not be less than 10 %.
The external output capacitor should not be too large (recommend < 10 μF), otherwise ripple will increase
dramatically.
Operation under 10 % load will not damage the converter. However, they may not meet all specification listed
All specifications measured at Ta 25 °C, humidity < 75 %, nominal input voltage and rated output load unless
otherwise specified.

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.
