I was curious to know, I can't find a Denso specification but I did find a website with a catalogue of would could be replacement alternators here:
http://www.woodauto.com/pdf/DEN2013.pdf and on page 47 you should find what I believe is the MR2 part 27060-22100 showing as 80A. If there was a Denso specification somewhere then it would probably have a graph that showed output vs. RPM.

Do you mean in volts?

12 volt no ignition.

13~14 volts ignition on and alternater
Is charging the battary.

If the volts for the alternator is lower
Then 12volts or goes from 11 to 12 volts while
Engine running ,  is a indecation alternator is broke
Or worn out....
