I am trying to use LM317T as a current regulator and the setup is from its data sheet. I couldn't get it to work.
Here is the datesheet of lm317t
I want a constant output current of 10uA when input voltage is changed from 3V to 2V. Since the internal reference voltage between output and adj is 1.25V, I put a resistors of 125kohm from adj to output.
I am getting very high currents like 3mA and I can't figure out why. I appreciate all your help.
