Hi,
I want to generate 1.8V (1.6-2.2 is ok) for a very low power application (active RFID, needs about 150uA). Batteries are unfortunately not available in this range (correct me if I am wrong). I want to getenrate a voltage suitable for my RFID, and it does not need to be well regualted. An LDO is out as it will just burn power, similar for a simple R divider. I'd rather not go down the roade of switching regulators if I can avoid it.
So im thinking along the lines of diode. Could I just put a 1.2V Vf diode between the battery and load? I thought about a zener with breakdown of 1.8V but wont this just short out higher voltages and quickly drain the battery
Tnx
