Hi everyone.
I am trying to build a double power supply, a simple one with lm 317 and lm337 - nothing special.
The positive rail works ok, also the negative rail but on negative the minimum voltage is -0.7V instead of -1.25. I used lm 337t p+ , two of them with the same result.
What is happening?
Thank you in advance
