I found the technique mentioned in this ariticle ( https://www.analog.com/en/technical-articles/increasing-output-current-of-the-ultralow-noise-ultrahigh-psrr-lt3042-200ma-linear-regulator.html ) quite applicable for my application, where high current, low-noise power supply is needed. However, the LT3042 only goes up to 20V. I would like to go to 40V with parts like LT3055/LT3065, or even higher voltage with LT3013. Is there any obvious caveat I should be careful about when applying this technique to other parts? And is there any good learning material for how to ensure the stability of the overall circuit?
