Use VOUT33 to power other devices

Hello,

 

Can I use the VOUT33 pin to power other devices? It seems that it is pretty stable under 120mA and my board should be using far less than that.

 

If I have a dual power source option (5V via USB/VREGIN, or 3.3V from elsewhere) but only one of then will remain active at a given time (user choice), can I connect the VOUT33 and the 3.3V straight to each other without damaging the MCU? Maybe adding a schottky between them? I am using a KL43 chip.

 

Thx
