Hello
Now I'm working on development using the LT3081 and LT3090.
It is a simple circuit in which the input voltage to the SET pin of LT3081 and LT3090 is output to Vout (Vout = same to SET pin voltage).
I have something curious about my circuit now.
In the picture above, I would like to know the proper resistor values of R7 of LT3090 and R9 of LT3081.(Simulation is no problem with 49.9Kohm.)
Is there any problem with the resistance of SET pin??
If you know, please recommend the resistance value.
Have fun~!!!
Thanks for the post. Avoid driving SET away from OUT as I discuss in this post titled "LT3083 output not zero when set pin grounded.".
Thank you for your reply.
But, I don't understand your replay.
what does mean "Avoid driving SET away from OUT"??
Just, I want to (SET pin Voltage = LT30XX's OUT pin Voltage).
So, Is there no need for the resistor of the set pin??
Or is it okay to put it with a 49.9Kohm resistor?
