It's designed to power USB signalling interface.. why not to put an external $0.05 LDO?

PCB area is not enough, if DECUSB can be used as 3.3V power supply, it will be very helpful.

It can power USB signalling interface, theoretically it can power a sensor or a MCU?

or its current load capacity is not enough?
