The NMTTLD6S5MC offers short circuit protection at low ambient temperatures from -40°C to the temperatures shown in the below graph, when the output power lines
are shorted together or to zero volts out.
Short circuit of data lines are undefined, all data lines should be properly used or teminated via a high impedance to their respective ground

Minimum load
The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.
