Voltage regulator dropout

[eng1]

Went and checked the parts. Have the 1N5822, and some 100 uH inductors. Not sure about the rating, about the size of a 1 watt resistor. Didn't dig out the L/C meter (batteries probably dead), but the bands work the same as resistors if I remember correctly, they are silver-brown-black-brown...

Those look like RF chokes. You have to look for 'power inductors'. There are both t.h. and SMD versions; lots of images on Google.

Guess I'll need to break out the L/C meter and do some searching. I know I have a bunch I never sorted. Don't remember any markings, so no way to determine power ratings. Guess if its not up to the task, a little smoke is always fun... Got a hunch most will handle 1/2 okay (for a while) though.
