I don't really took it like that, just said how is it going to load up the 3.3V line until it drops? Makes no sense.
So either the ldo is working at the very limit of its specs or got damaged.
Thanks, I hope you enjoy it! It could boot much faster, the boot screen is shown for 1 second just to look cool.
Try lifting the ldo output and connecting and amp meter, shouldn't be more than few mA.
Anyways, it would heat up badly if the current was too high, it's directly regulating from 24V, dissipating 0.42W/mA.
5mA(1W) would be already too much, I doubt that small package can get rid of the heat without thermal pads and thick traces.
Typed some funny thing at the calculator!
