Accuracy of a 15v rail

Hi, @baffled2023

I am not sure why they used a variable reg if they wanted 15v?
What does having a variable output gain you? (assuming you want dead on 15v).

They make this regulator in a 15v fixed output. Surely that would have been better than the -adj version

Because if you look at the spec for a fixed 15V regulator, it would probably fall outside the requirements for your circuit.

By making it adjustable, with a calibrated volt meter, you can set it to 15V to YOUR tolerances.

Does this 15V supply power any other components on the board?
