Run 5v from 12v port with LM1084
« on: January 17, 2017, 02:31:13 AM »
Can it be done?  I realize I could run half a F16 on 5V but I only have 1 or 2 things that need 5v...  According to specs it's 5A.  http://www.ti.com/lit/ds/symlink/lm1084.pdf

The spec sheet for the LM1804 voltage regulator shows a tolerance of "up to 25volts" above the output. So a 5volt version could handle 30volts. I wouldn't do that, but 12v should be no problem.

Cool.  I will do some long term testing before launching anything.  Thanks Jon!
