Power test smr4 mkII

hi there am getting -4.7v and +5.0v at all the test points is this acceptable and if not what can be causing the low negative reading.
thanks

Production variances are the keyword. Anyway these readings are absolutely ok.

That’s just a little bit more than 5%, so it’s fine…

Is that from a kit or self-sourced?

self sourced. could it be because i used a 470uf for c20 and a 220uf for c30.

Which 7905 did you get? There are many variants of it, with different tolerances. The one I used for the kit has 2% tolerance, but the 5% variant is more common.

L7905cv yep it has 4% tolerance so i guess thats it, thanks again
