The circuit reference is from Jung, Walt Jung has been designing voltage regulators since 1961
Very low noise, very low output impedance, very suitable for pre-stage, DAC precision power supply. It should be one of the best circuits in all discrete regulators today
Stop using a simple three-terminal LDO. The experimental results tell us that this is not an opponent at all. Regardless of the noise, response, and impedance, SJR can be said to be a big win.
