Notes:
The output requires a minimum 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.
Any condition of dual output (3.3Vout, 5Vout) rated lout current do not exceed 8A of total output currents.
