Hi friends,
I wish to know how to convert a 6V 4Ah battery supply to usable current of range "mA". I have looked into lot of forums and found that using of LM7805 will have good result but the output current will be around 1A. But i wish to have the current in the range of 500mA for using this a backup battery for Microcontroller projects which requiers 5V and mA of current. Also i feel that the battery provide a long time supply in mobile time ie, while using circuit outside without any domestic current supply. Please help me out in this situation.
