"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.
Thanks Richard, but I'm not comfortable with giving out my mailing address. Thanks for the offer though. I guess I have to buy the right version this time.
Any ideas? Does everyone think I got duds? Or is there something related to the ADJ marking on them.
There is an adjustable version of the LM1084, and that is what you have.

@Tech... How Many do you need? I have some LM1084 (5V versions)... Just need your mailing address so I can mail them out to you....

No worries... I was going to give you them for free... If you want them email me at ryersonroofing(at)yahoo dot com
:)
These look like the right ones, don't they?

Yes, according to the ebay title, they would appear to be the ones you seek.
Hi @Technopro,
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
