Op Amp "Internal ground"

the experiment

[Eof]

some OP-Amp based regulator check ups

Minimal

Improved -- It seems the LT1086-12 model sets up a little "Show"here . . .

No concert v. -- although it simulates fine /!\ there'll be a point of concern selecting the proper xx78Lxx as the one i got was "factory tuned" to something 12.4V ((+3.3% systematical ? = no problem - the datasheet specifies ±(5% systematic ±0.75% line- (±0.417% load regulation)) =/!\ 12±0.74V )) . . . while the above grid shows some 9±0.00003V load regulation (which in practice should be expected at least 10x worse OR ±0.0033% load regulation) . . . blah, blah

Dual Op.Amp v.

just a draft test for the 2-clones on the first image - /!\ it's (the test's) not scientifically designed - there's much nothing to conclude about it /!\

Regulators test

Custom based on behavioral Op.Amp model (voluntary random LT1097 - the very first i got interested in)

LT1086 behavioral model

LM317 model based on Spice discreet component models

what it seems - is - that with the high power output loads the basic connection scheme works best for the LM317 (i didn't test 'em all of course)
