The VIN to VOUT voltage drop in the device is determined by the RON of the device and the load current. The RON of the device depends upon the VIN and VBIAS conditions of the device. Refer to the RON specification of the device in the Electrical Characteristics (VBIAS = 5 V) and Electrical Characteristics (VBIAS = 2.5 V). After the RON of the device is determined based upon the VIN and VBIAS conditions, use Equation 2 to calculate the VIN to VOUT voltage drop:
An appropriate ILOAD must be chosen such that the IMAX specification of the device is not violated.
