Hi,
Now I'm referring the reference circuit Fig 2 in page 22 of following document that configure current reference with voltage reference IC, FET and buffer amp.

But now I'm considering to configure current reference with REF3450 and FET, no buffer amp as attached. Do you think any concern for this configuration?
