Ok, I'm sure you have enought knowledge about electronics scheme but I'm not the same.
I've read datasheet and that's my output:
My questions:
1 - I can't define R2 (don't know Vout or VR2)
2 - is right the R1 value?
3 - is right the R3 value?
4 - how determinate R on pin5 (need it or not?)
5 - how can I determinate Vled=3V?
Please help me understand (I don't want simply value of R)
Many thanks
Alex
