Minimum input voltage defined in the recommended operating conditions is the maximum specified output voltage plus dropout voltage at the
maximum specified load range. Since dropout voltage is a function of output current, the usable range can be extended for lighter loads. To
calculate the minimum input voltage for your maximum output current, use the following equation: VI(min) = VO(max) + VDO(max load)
Because the TPS7101 s programmable, rDS(on) should be used to calculate VDO before applying the above equation. The equation for calculating
VDO from rDS(on) is given in Note 2 in the electrical characteristics table. The minimum value of 2.5 V is the absolute lower limit for the
recommended input voltage range for the TPS7101.
