didn't you reverse the 78L05 ? |

I am pretty sure that i didnt. Lets see, if the straight face its towards me the first pin should be output, the second one should be ground and the third one should be the input, right? |

8.6V at C21+ seems ok. what do you have at the output of the 78L05 ( or C17+) ? |
| donthack22:
I got 5V, but again i have to mention that i got 5 V only if I do what Arznei told me. If i dont i get like 2 V. My issue now is that even if i got 5V, i cant get -5v from ICL7660, io get only around -3.40V. I know for sure that before i connected all integrated circuits ( tl082, ad620, 4053) i got -5V and i dont know what may be the problem. I first thought that maybe ICL 7660 doesnt provide enough current, but this circuits doesnt require a lot of current. |
