Hi,
I'm trying to set up an LM337 adjustable negative voltage regulator to give -18V when supplied with ≈-21V at 250mA. Can someone please advise on what resistor combinations I would need to attain this? When I say resistor values I mean according to the diagram in the datasheet, if anyone knows of any other set ups feel free to recommend them.
I had a look on the internet for some calculators for this chip, but they all asked for "Iadj" and I've got no idea what this is :S.
Thanks!
