Default 6.5+ Volt In, 5V 7.5A Out

Was ordering some more LT1185 LDO regulators that I use for various things... came across a this gem LT1083 LDO high output regulator. What impressed me at first was the high current output with only 3 pins!

LT1083 - 7.5A, 5A, 3A Low Dropout Positive Adjustable Regulators - Linear Technology

This is just as simple as the common LM317 circuit, but is good for your higher powered diodes!

I know a lot of people favor the boost circuits, which is awesome... some of us like the big 2 cell stuff. I want to put a big array in a 4-D cell mag. I could theoretically power maybe 3 of these. Imagine this:
3x 7.5A = 22.5A
-How many diodes is this?
1.5A per M140, 22.5/1.5 = 15 Diodes.

now.. I know there isn't even enough space for this in a maglite, but the idea is fun. 15 M140s in array at 1.5W ish, you'd have a 22W handheld laser.
