Hi
Im looking for a simple regulated split rail power supply (+5v GND -5v) from a 12-15v DC supply
Its for a low current application <100mA, but the +5v rail will supply more components (ie Pic chip/real time clock/LCD ect) so will have more current flow, the -5v supply only feeding the negative supply rail on a op-amp and a sensor.
I did see a diagram a while back that used a 7805 and 7905 5v regulator ICs, but cant remember where it is!
Thanks
