Hi
I have a 2000 mAh 3,7 V (nominal) mobile phone battery that I would like to charge super simply. Mostly because I don't have space for circuit board.
I ordered 5,5 V, 110 mA solar panel. I need some kind of regulation because LiPo cell voltage should not go over 4,2 V
My idea was to use AP2125-4.2 fixed LDO. It outputs 4,2 V. Max output current is 300 mA, so I don't need over current protection between solar and LDO.
Will this LDO drain my battery if solar panel won't produce voltage? meaning output voltage is higher than its input.
