Well im going back and forth between building the salas shunt regulator and using what i got now:
astec atv351

http://datasheet.octopart.com/ATV351-Astec-Power-datasheet-119783.pdf





it uses a ua723cn as a regulator

and a 2n6383 as the external transistor

Specs on the supply say its good for 3mv ripple, reg chip says 2.5uv noise with 80db rejection.


It will be used to power:
amb gamma 2 dac
active pga 2030 volume control
dcb1 buffer
