... for a aune dac, ref: http://www.head-fi.org/forum/thread/505235/replace-lm1117-with-78xx-regulator#post_6824241
i don't think i have this figured out, need some expertise.
i want to replace these LM1117 with dexa super regulators, but i don't know whether to use positive or negative regulators.
my multimeter reads positive voltage at the LM1117 pins, but it looks like they are designated as negative as printed on the pcb.
i've looked at the data sheet for LM1117 - http://www.advanced-monolithic.com/pdf/ds1117.pdf , but don't know enough about this to make a decision.
i'm aware of the pinouts and dropout, and i think all i need to know is whether to get dexa 78xx, or 79xx.
