Hi,
Just wanted to know what happens when an input voltage dips below the drop out voltage for a linear regulator. In this case, I want to charge up 4 lithium iron phosphate (not li-ion) at about 3.5v ea in series = 14v...FROM a solar panel... which, being rated at 18 volts (and higher in cold temps) can, in higher temps, drop considerably. Now, the voltage difference in the lm338 specs say like 2.5 volts.
If, theoretically, the panel only put out 15v, and the LM338 was set to 14v, I know I would lose voltage, but I would lose current too?
Thanks
