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 the maximum load current used in a given application, use the following equation:
VI(min)
Because the TPS7201 is 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 3 under the TPS7201 electrical characteristics table. The minimum value of 3 V is the absolute
lower limit for the recommended input-voltage range for the TPS7201.
This device is in the product preview stage of development. Please contact the local TI sales office for availability.
