Perfect test. Following possible overloading of R-78E5.0-0.5, what maximum load could be applied to R-785.0-1.0 ?

1A is not enough for me :)

Did you try to overload it?

Thank you!

Great analysis!
But, in the worst case, if R-78C burns out, what would be on the output? How many Volts? Zero or Vin???
Thank you!

Nice post John,

I had not heard of the new DC regulator, but power supplies are one of the largest energy loss items of most circuits.

I may have to take a look at these new chips.
