Ok i was tired of using stupid batteries and having to recharge off board. So i decided to make a LiPo charger but with a nice 300mA 3.3v regulator on board.
I have not made it yet tho… i just finished the design and schematics and so far its nice and small and should work fine!
The LiPo charging will be controlled via MCP73831
The 3.3v @ 300mA out will be regulated using … MCP1802
Seems like they both are Microchip parts and have same foot print which is a SOT-23-5.. slightly bigger than a normal SOT-23.. since it has 5 pins instead of 3…
I would love some comments…
