Ok so I have a circuit consisting of three components, their +'s and -'s connected to jumper strips so that I can connect the terminals of the battery to each strip. The 12V battery puts out ~12.6 volts when hooked up but as is drains, it drops slightly and the output of the components have to be recalibrated (output is dependent on input voltage). To remedy this I got a small 12v regulator chip that when hooked up to the battery alone puts out 11.65V which is fine (my thinking is that the circuit will get a constant 11.65v until the battery drops to below 11.65v). My problem is when I connect the regulator between the battery and the jumper strips with the circuit ground connected to the regulator ground and that connected to the neg battery terminal, I no longer get 11.65v but instead 10.7V at the jumper strips.

Why would I get the same voltage at the terminals and entrance to the circuit with the battery alone, but a drop in voltage (11.65v to 10.7v) at the output of the regulator as soon as the circuit is connected?

Did that make sense? I'll snap a pic if I need to. Thanks
