Duncan,
?
Thanks for this; for some reason I had to really play with the circuit it get it to produce reasonable voltages in both scenarios.
This is the regulator I was looking at https://www.ti.com/lit/ds/symlink/lm1084.pdf?ts=1721541195139&ref_url=https%253A%252F%252Fwww.mouser.com%252F

The start up current is 2.5>3A and running 240-260mA so this is what I ended up with.
