I made an Lm317 circuit and I'm not sure which to trust measuring the current. With a test load for BR (6 1n4001s and a 10ohm resistor) i measure .850V, which should be 85mA. I measured the current with my multimeter's ammeter mode measured .220 amps with no other load. With the equation for lm317, using 38ohms, it should be giving 32mA. I'm powering this with a 9v and using a 10µF tantalum cap on the output. Which should I trust for the output? (I hooked up a LPC-815 and could tell it was higher than 32mA).
Thanks,
Andy
