Have you measured it's dynamic performance?
I did some spice simulations some time ago and noticed that there are
some load conditions where this circuit is very close to oscillation
(ie load changes lead to heavy ringing)....of course, this is under
the assumption that the spice model of the LT3042 is accurate in that
regard.
