When lit, it drops to between 4.70 and 4.74V.
The Arduino Uno is power by 12V batteries. I'm getting 5.02V on the Arduino when the project is running. When I lit the LCD, the voltage is still 5.02V. ...
The voltage on the TMP36 is 5.02V without the LCD lit. When lit, it drops to between 4.70 and 4.74V. That is my problem, and I don't know how to solve it.
The question is how does that happen if your Arduino +5 regulated voltage stays constant?
I agree with everyone that if your V+ voltage drops from 5V to 4.xxV

You can isolate your TMP36 from that by disconnecting it from the power & ground bus on the breadboard and running separate power and ground jumpers direct from the Arduino.
