Hi,
IF we consider The 317 has a max ref voltage and a max Iadj current ... those readings are possible ... ( your 317 is "not so good" , Roger !!! )
But that also mean ANOTHER 317 could damage the DS 1804 ...
this design won't be good for series production ...
Now, Roger, there's another point to verify ... your PCB tracks !!! are they sufficient to hold the required current ...
And overall ... did you use a "star" config to link your ground tracks ???
( maximum care for R5 ground return path ...)

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
