Output Adjustment all single output models:
The output can be adjusted upward by using the output
adjust (pin3). The resistance between output adjust (pin 3)
and output common (pin 4) will determine the magnitude of
the increase in the output. The table above is applicable
only to MHE2805S and MLP2805S.
