Do you really need 1A and 35V in? That would dissipate way too much heat to be practical.
For lower currents, LP2951 isn't bad - 30V and 75uA Iq, but only 100mA out
There's a couple of 5V to 24V DCDC bricks that run off it, so it does need at least 400mA.
But yeah, I just picked 1A to give it some extra room.
The 7805 used now does get very warm, but it's on a large 6 layer 3oz pcb, so isn't really a problem.
I think the solution is to split the power rails up a bit. Have a lower current reg to run the MCU that has low quiescent and then a pfet to switch on a 7805 that controls everything else.
I was more just curious why there wasn't a cheap drop in 7805 replacement with much lower quiescent.
Given the 7805 is very old tech.
