J310 is rated at 25 volts, so it should work fine at least to that level. It might work at higher voltages, but the risk of failure increases exponentially.
The LM117 is still within its ratings all the way up to 40V. It will shut down if it gets too hot.
Looked at the LM117 specs and 1.5 ma is below it's min current specs.
