(1)
This voltage is for internal usages only. No external DC loading should be applied.
(2)
This represents additional current that can be supplied to the application from the VUSB terminal beyond the needs of the USB
operation.
(3)
A current overload will be detected when the total current supplied from the USB LDO, including IUSB_EXT, exceeds this value.
(4)
Does not include current contribution of Rpu and Rpd as outlined in the USB specification.
