9.2.2.1 Maximum Voltage Drop and On-Resistance
At 3.6-V input voltage, with a maximum voltage drop tolerance of 1%, the TPS22971 has a typical RON of 6.7 mΩ. The rail is supplying 10 mA of current; the voltage drop for a rail is calculated based on Equation 10.
Equation 10. 
Equation 11. 
The maximum voltage drop is 1% which is 36 mV. The voltage drop caused by the load current across the on resistance is 0.067 mV.
