NOTE: VOUTset is the nominal output voltage that A6500A is set to, for example, 3.3V.
VDROP = VIN - (VOUT * 0.98), in which VOUT is the output voltage when VIN = VOUTset + 1.0V at different output current, and VIN is the
input voltage at which the output voltage becomes 98% of VOUT after gradually decreasing the input voltage.
