I want to regulate a voltage suppose 60 V, but I only have an LM317 (or any similar voltage regulator IC) with voltage regulation range of 30 V max.
Is there any way I can use a combination of two or more LM317s to make a voltage regulator that can regulate 60 V (or more)?
Can I feed the positive output of one LM317 as ground in the 2nd LM317, and measure the voltage between the output of the 2nd LM317 and ground of the 1st LM317?
I do not have any particular use or reason to ask this question. I am just curious if I can do that. This is just a hypothetical situation.
