Hello, 

VDD50USB on STM32H755II is powered from external 3.3V supply. What is the general use current consumption of the internal USB regulator? 

Thanks!

    Hi @drad1 

    VDD50USB can be supplied through the USB cable to generate the VDD33USB via the
    USB internal regulator. The current consumed through the VDD50USB port on the STM32H755XI MCU is around 10mA.
