PSU design?

[Tony Allgood]

The 723 is a great chip. Go for it. Quiter and more stable. It will need
an external transistor. How about a 18V split rail with the 723s and
then a 7815 and a 7915 on each module? See the archive for more details,
as this has been covered before.

Subject: PSU design?


I'm about to build  a new +/-15 v PSU. Currently I'm choosing between
two
designs, either one based on 7815/7915 or the Digisound 80 design using
two uA723C's.

It's meant power a modular unit with your average mix of oscillators,
filters, mixers,  weirdo circuits etc. I probably need a second +5 v PSU
to drive those digital ICs but I already have a small computer PSU for
this.

Any thoughts on what to design to use?
