I have this circuit which needs to be powered by batteries and I am looking at a 6V SLA.
The uC datasheet indicates a voltage range of 2.0V to 5.5V and it will be driving a small DC motor that requires 1.5V to 4.5V. If possible I am trying to avoid using a regulator.
I was thinking of using a diode (D4) in series with the supply to drop the voltage to the PIC to 5.3V and another diode (D3) to further drop the voltage to the motor down to 4.6V.
Does this makes sens or do I have other alternatives?

Thanks,
