tiny85 self power-off

I thought R3 was necessary to limit the inrush current if the Fet?

I do have caps on the LDO as per data sheet yes.

The N channel is an IRL540N, the P is a SUP53P06-20. Both just what I had on hand. This was supposed to be a one day project hah.

Didn't look into the diodes Tom, what issue might it cause if they don't? Thanks for redrawing.

I'll check where R3 is, it may be right and may have just incorrectly drawn it. My perfboard is a bit of a bird's nest
