It seems that I have run into a conundrum of sorts.
I am working on a small LM317 driver, and I set it up the normal way... with the Battery+ connected to the pill, then the pill connected to the right pin, and then an array of 1Ohm resistors in a 2x2, and then that leads directly to the back tab, which is also where the output lead goes.
I have a cap and a diode attached to the same through-hole that the last resistor attaches to (so that they are parallel) and then grounded the cap and diode (connected to the same ground that the test load ground lead goes to).
I checked my resistor array's resistance and it is 1 Ohm, and I checked my test-load's resistance and it was 1 Ohm as well.
YET... I continually get readings of 2.2-2.3V corresponding to 2.2-2.3A instead of the 1.25A I should be getting....
HELP!
