Note: When trimming the output high, I_o vs. Ambient is derated by power. i.e.: from Graph 2, find the maximum current at the desired
ambient and airflow, and multiply this current by the nominal voltage (5V) to get the maximum power. Divide this power by the desired
trimmed high voltage to get the maximum current at that ambient. When trimming low, the maximum current stays the same as shown in
graph 2.
