[sdiy] Voltage regulation tracking using LM723

[thx1138]

Hi SDIY folks,


I am rebuilding a new Dual VCO design in discrete form and in the past I
used a LM723 voltage tracking circuit for power supply to my modules.

I had been using +/- 18.5 VDC and regulated it to +/- 15 VDC in past designs
with pretty good results.

Has anyone any belief or knowledge of a better Voltage tracking device or
circuit to examine? What power connectors do you folks recommend for
commonality sake?

Let's assume of course that the LM723 is still plentiful.

I refuse to use SSM or CEM chips as I want this to be a sustainable design
and not worry about Obsolete custom chips dissapearing.

I have a DSP56725 based design that can generate multiple waveforms in
parallel with wave shaping done in the 2nd Core of the DSP.

We just announced a 10 year manufacturing longevity to the DSPx672x devices.

These are 2 separate modules, but I want to build the analog one first and I
am getting close to closing the schematic.
