Hi, am trying to get an Aref input on a Uno. Wanted to get a lower voltage than the 1.1 internal so tried a 0.6V Precision shunt regulator, a Zetex ZXRE060.
Built a little shunt regulator circuit and the Vout is .6V but when I connect to the Aref, the voltage drops to 0. Here is the link - am using the circuit ifn figure 3 -http://www.diodes.com/datasheets/ZXRE060.pdf
There is something on the data sheet that says there is a precision internal reference that can turn off the Vout which I do not understand.
I am inputting 3.3V from the Uno. (device will accept 2-18V input)
Would changing the value of the resistor or capacitors allow the Vout to connect to the Aref without dropping to 0?
Perhaps I chose the wrong device to act as a voltage regulator?
Thoughts or suggestions?
Thanks
