Below is the lab power supply schematic that I would emulate from National Semiconductor linear brief 28. Instead of using expensive LM395 integrated power transistors, the power pass element could be replaced with suitable integrated regulators or bare transistors or some combination of the two.
that's a nice circuit (unlike the other ones ) but it looks like LM308 is no longer available and LM101 is hard to find and very expensive, although there are cheap LM301 in sot8 package from onsemi.
replacing those opamps with modern parts would require a different compensation network and careful selection of parts complying with the same input range (and other features) of the original ones or mirroring the design (regarding polarity) to rather use the so-called single power supply opamps that usually include the negative rail as input range.
The LM101 is the military temperature range version of the LM301 and the LM301 can be replaced with the LM301A which is readily available. (1) The LM308 as used here may be replaced with practically any device although the LT1008 from Linear Technology is an improved direct replacement. The LT1012 and LT1097 are also improved replacements which include internal compensation.
The LM301A would be very difficult to replace in this circuit because:
1. Its input common mode range includes the positive supply making it especially suitable for a high side current sense amplifier or in this case, a high side current error amplifier. There are many modern rail-to-rail input parts and several older JFET input parts which meet this requirement however ...
2. Its external compensation pin can is used here to clamp its output to improve overload recovery time. The list of modern operational amplifiers which can support this mode of operation is very short. The aforementioned LT1008, LT1012, and LT1097 are the only common modern possibilities I am aware of. Analog Devices makes some parts which might be able to do this but since they do not publish schematics, there is no way to know without reverse engineering them.
I mostly listed this example circuit as something to study because it includes many lessons in practical design like low output capacitance, active pull-down, and direct high side current sensing. There are ways to externally clamp an internally compensated operational amplifier however they get complicated very quickly so it is very rare.
(1) The LM301A is an LM301 with improved input bias current over temperature. The LM301 was only produced for a very short time before being replaced with the A version.
