PIC18F47K42 Curiosity Nano

3.3.3 VBUS Output Pin

PIC18F47K42 Curiosity Nano has a VBUS output pin which can be used to power external components that need a 5V supply. The VBUS output pin has a PTC fuse to protect the USB against short circuits. A side effect of the PTC fuse is a voltage drop on the VBUS output with higher current loads. The chart below shows the voltage versus the current load of the VBUS output.
