Actually, the next step is to build the prototype (breadboard) and fix all the things that don't work right.Next step will be to make a PCB.
Forgive me if this is a dumb question: are you saying you have already built up three operating prototype boards?@bountyhunter First prototipe was a Lm723 power supply , then I make a second one and add pic and operationals to measure current and setup the voltage target and current target. If I can remove LM723 will be great.
This is the third prototipe and the current limiting has not been proven yeat, also the second prototipe had a 4x7dig display, now it has been replaced with LCD 2 rows.
I will come back with update schematic.
You certainly can. The schematic I attached is a complete generic linear reg with both voltage and current control loops (current limiting is included). The 723 is a low performance chip to build cheap power supplies.If I can remove LM723 will be great.
