[NSRCA-discussion] regulators

[Robert Mairs]

I've got a Jaico that regulates to 6.11 volts.   Using a 480 mah TP lipo, 
and the Jaico, I got the following.

no load, 6.11v
500mah load, 5.72v
1A load, 5.63v
1.5A load, 5.54v

Just with the battery, no regulator I get

no load, 8.2v
500mah, 7.84v
1A, 7.51v
1.5A, 7.2v

I don't understand.  Why doesn't the regulated voltage stay at 6.11v with a 
load?  I always thought using a regulator was supposed to give you a 
constant voltage so the servos reaction would always be the same, yet it 
acts just like a battery,  just not as great a drop off it seems.
