NX5P3290: The output has a voltage drop of about 0.1V

[Peiwu]

Hi All:

I used NX5P3290UKZ in my design, but when the VIN is 5V, the VBUS output is only about 4.9V (without load). I didn't see any description of voltage drop in the datasheet. Is this correct? What is the cause? 

Theoretically, the output voltage should be equal to the input voltage.

My schematic is as follows:

Hello,

NX5P3290 has a function to make VBUS=Vin-70mV, so yes It is normal to have a small drop in output with no load.

Regards.
