The characteristic curves are similar across the
LT6654 family. Curves from the LT6654-1.25, LT6654-2.5 and the LT6654-5 represent the full range of typical performance of all
voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output.
