uSupply BASIC

newbie666:
I've just finished watching a series of Dave's videos on uCurrent and I rather liked the "basic" version of the supply without uC. I decided to draw a schematic based on the video and design a PCB. Since these are my first steps with eagle / layout, please have a look at my PCB. I've done one ground pour on the bottom layer, is it a good idea or other grounding scheme would be preferred?

A couple of questions about the PSU:

* What should I do with LT1009 if I want to skip the trimmer? Should I just leave the ADJ pin unconnected?

* I've checked most of the component ratings and I haven't found any reason this circuit wouldn't work up to 15V which would be useful for my audio projects. Am I missing something?
newbie666:
OK, rev2:

* fixed a feedback loop of voltage set opamp (was missing 2 resistors)
* added optional resistor between voltage set pot and ground to be able to set minimum output voltage
* changed connectors for outboard pots / led

As always - any comments are more than welcome.

I've ordered boards at jlcpcb but I've submitted old gerbers with the bug  |O |O

I'll post some pictures when they arrive.

Too bad man, hope you can bodge that bug out...

Did you received the boards?
