Hi
UCD90320 VREFA+ specification is 2.4V~3V, but your reference design used 3V output LDO (REF5030A) for UCD90320 VREFA+.
That LDO(REF5030A) could be over 3V that out of VREFA+ specification. Does it have any risk for this design?
Why don't use 2.5V~2.8V LDO for the VREFA+?
Thank you so much.
Frank
