Battery voltage regulated power supply with positive and negative output
I would like to design a cost effiecient and effective voltage regulated power supply, such that i can have +12V and -12V output.
But the challenge is that i am going to use a +12V Battery as source [No AC source].Well my design in my mind is:
BATTERY--->REGULATOR---->[ +12V, GND ]and [-12V, GND]
can anybody give your suggestion??? i don't want to use readymade costly chips, but i tried to use regulators like 7812 or 7912.. but the challenge was finding the ground..:???:
circuits with OPAMP or transistors might be very much appreciated.
looking forward for your suggestions.
