STM32L073RZ 5V pin current limit

[Josh636]

I was wondering what the maximum current limit is for the 5V output pin. I looked at the datasheets but couldn't figure it out.

This depends on your setting , on JP5 : (here jp2, MB1364)

So, as you set it, from USB->St-link , about 100mA (because from USB, and st-link also needs current).

Up to 800mA , if you supply it by the VIN (external in) .

See circuit : on STM , for your board -> CAD resources , you will find it.
