The MT5A series required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not
damage these devices, however they may not meet all listed specification.
BELLCORE TR-NWT-000332. Case 1：
50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
M1 version is more efficient, therefore, it can be operated in a more extensive temperature range
than standard and M2 version
Maximum value at nominal input voltage and full load of standard type.
Typical value at nominal input voltage and full load
There is no pin at PIN10 & PIN15 for MT5A-W series
