Hi all. I've got a problem with a Mohgasm linear assembly I am attempting.
I am trying to set one @ ~300mA. I've done the math: 1.25/R=I(amps) and have come up w/ a resistance value of 4.2 Ohms.
I've assembled a couple of these now. Matt was so very kind to give me the makings for a few of them. So, I'm not unfamiliar with assembling them.
My problem is that despite all of my attempts, including throwing on just a 1Ohm resistor, and swapping ICs, and I cannot force out more than 170mA w/ 8V from the batteries.
Any ideas what I am doing wrong? Could I have damaged the IC with excesive heat when soldering it on? Could caps being placed improperly cause this kind of anomaly?
Thank you in advance for your help.
