Hi,
I would like to implement these in my NAPST which has four LT1085CT's in it at the moment.
I am a little confused as to what is the ultimate build on these things.
I see the schematic and photo on post #164, which I understand is the way it has been implemented, but recently, after a query to Teddy (I'm sure he won't mind me quoting him), he said,
"In my opinion C2 should be connected between the ground and the emitter of Q1. I would also add a resistor in parallel to C1 to have at least a 2v dropout on the pre regulator".
I'm not sure what to do here so I am hoping that one of you knowledgeable techo's here will be able to help.
Which method will work better and what resistor value should be used in parallel to C1 if used?
Would the BC547C be fine for this use in this area?
Thanks,
Pete.
