I need to provide a backup voltage to a device, the current requirement is 20uA. The device is battery powered. It is my understanding that zener regulator requires enough current to put the zener into regulation which would be too much for our battery life.
I know there are voltage references out there for this but they all seem tobe in the $2 range, a bit pricey.
Any elegant solutions?
Thanks
