Hi, looking to power the NUCLEO-F767ZI off another board (which has a TPSM843320 buck), any issues with this as the 5V rail (E5V), on the dev board you have LD1117 LDO, but the rail I can provide isn’t high enough for the dropout. 

 

Any spec on ripple or how clean the E5V rail should be? Seems to only be used by STLINK and USB.
