Thanks, that'll be v2.0 I think.Or you could put 560 ohms where D2 is.
Or make the pot 2K and place that in series with 8.2K 5% or 8.87K 1% for a finer range of adjustment.
These are not important changes. Just options, mostly to demonstrate the kind of fine tuning methods that come from experience in designing analog circuits.
Thanks, yes, I did read up on that but didn't show it on the diagram, I only used a generic resistor diagramJust connect the pot wiper (not shown) to common.
That would be true for a P-MOSFET but this is an N-MOSFET so the source (S) is the output (as shown).I can see the G goes to GATE but am I correct in thinking that the D goes to V-OUT & S to V-IN?
love it, thanks chap....little pointy thing.
The wiper can be connected as shown or to ground.Is this correct - pins labelled for ease?View attachment 128902
Looks like it's clockwise from 1 to 3: http://docs-europe.electrocomponents.com/webdocs/15aa/0900766b815aa64c.pdfThe wiper can be connected as shown or to ground.
Typically you want a clockwise turning of the pot knob to increase the trip voltage (reduce the resistance).
For that you need to know towards which end (1 or 3) the wiper moves with rotation (usually shown in the pot data sheet).
If you don't care which pot knob direction increases the voltage then the connection shown will certainly work.
Connecting as you show will increase the resistance for a clockwise rotation, reducing the trip point voltage.Looks like it's clockwise from 1 to 3: http://docs-europe.electrocomponents.com/webdocs/15aa/0900766b815aa64c.pdf
So I am good yeah?
Would it function any differently connecting the wiper to GND?
Thank you.Connecting as you show will increase the resistance for a clockwise rotation, reducing the trip point voltage.
Connecting the wiper to ground will do the opposite.
