I'm making a +12V/-12V power supply (2.5A max. output current each) with voltage regulation and current limiter (+ option to go lower on voltage than 1.25V). In the datasheets, I've came across, that in the Datasheet, page 8, FIgure 20 that there's a current limiter BEFORE the voltage regulation, which didn't made much sense to me.
Isn't is supposed to be the voltage regulation first in a "row" here? Because if the current will be limited too low, there's not even necessarily that I could get 1.25V on the input of the "voltage LM-317"?
In the second photo, there's my schematic for the power supply with voltage segment before the current limiter. Is this the more correct one or is the one from the datasheet the one, which I should use?
I marked with red the voltage segment, while the current limiter is red.
