10.1.1 VIN to VOUT Voltage Drop
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 = 2 V to 2.5 V table of this data sheet. After the RON of the device is determined based upon the VIN and VBIAS conditions, use the following equation to calculate the VIN to VOUT voltage drop.
where
- ΔV = voltage drop from VIN to VOUT.
- ILOAD = load current.
- RON = On-resistance of the device for a specific VIN and VBIAS combination.
An appropriate ILOAD must be chosen such that the IMAX specification of the device is not violated.
