How much capacitor can VBUS use when using the USB function?  Datum:2017-04-26

The VBUS capacitors need to comply with the USB-IF specification inrush current. For USB 2.0, the USB-IF defined that inrush current could not exceed 50 uC. Therefore, if the VBUS normal voltage is 5.0V (Q = CV), the VBUS capacitor shall not exceed 10 uF.
Users need to design their own circuit, and adjust the VBUS capacitor. With the USB analysis tool USBET20 provided by USB-IF, user can see if the VBUS capacitor conforms to the USB-IF specification.
