Hey everyone.
Just making sure I'm correct on this, would this diagram be correct?
Thanks,

I use this setup, but there's hardly and light coming from lights I wired up. (Yes they do light up on 5V from another battery pack) Direct to the battery the lights are bright as day. Going from my science homework, do I need a resistor or something before the power enters the regulator?
Any ideas?
Here's a link to where I was told to use LM1084's.

YAY or NAY for these regulators

"The LM1084 is available in an adjustable version, which can set the output voltage with only two external resistors. It is also available in three fixed voltages: 3.3V, 5.0V and 12.0V. The fixed versions intergrate the adjust resistors.
"
My ability to read schematics is too out of practice to follow the diagram on that page, but apparently you use resisters to set the adjustable output.

You could still use the adjustable version of the LM1084 if you have a few common resistor values and follow the pictured diagram:
Use a R2 value of 1kohm and an R1 value of 330ohms and it should give you a value of 5V. Equation is 1.25V(1 + R2/R1) = 1.25V(1+1000/330) = 5.04V
I sure hope they are Robot-doc!
