TL431 Spice model variants´ TEST

presented as we go
► 1-st

► 2-nd

► 2-nd - in detail

wider range

component level models (sub circuits compared)

the best - upper two are the attempts to achieve better precision×frequency-rejection //// the reverse Vref´s emitter (EB) diode in Rank#(7) is a contemporary relic from an attempt to force the "Hot Start" for U4,U5 . . .

pulse e.g. stepped load response

overall ranking so far ...

? best CLM-s !!! for static operation . . .
. . . for undefined input the U5 e.g. X4 is likely better choice /// might be quite expensive regulator as the RF transistors cost $ 0.2÷1.0 per pcs.  /// (i can't comment nor recommend nor reject the macro models - but usually they are too optimistic !!!)

hi, hi - UPS! seems i used Amps insted of milli-Amps

that re-ranks the rank back to "Static" -- the red box is "for super cool experiments only!!" . . .
. . . so U2 // X1 the best CLM !!!

about LM113 Simulation

i donno - either i'm stupid , use wrong transistors or what's worse - this thing actually does not work in real ::

this is what GOOGLE thinks you should be happy with . . .

® TIF - opens fast & displays with Adobe Photoshop Elements , opens slow & displays with Nero PhotoSnap Viewer , opens but does not display with Microsoft Office Document Imaging (is a zip compressed while the less opt.-d 260KB LZW copy does!)

about :: FUCK - i uploaded an optimized 600dpi B&W 135KB (138 268 byte) TIFF image - now what GOOGLE doeas is "fuck your quality" - IT'S NOW NEARLY UNREADABLE JPG - thank you - thank you - thank you - thank you - thank you - thank you - thank you - thank you - thank you - thank you - thank you - thank you ... 

... why to write a web page is ► no one reads it anyway - ◄ such a predictive img formatting policy F;i ? why not XD (! IDIOTS)

... I GUESS I GONNA CANCEL THAT BLOG - along shot with the GOOGLE translations of my stuff ◄ this really sucks
. . . as i did proceed - v.1 ::

 a "fuzzy logic" induced "meet power" - spike reduction attempt (i din't want to discard/modify any of Ti components - assuming the schematic being authentic)

-------------------- - v.2 ::

??? both v.-s' simulations show a "strong" hysteresis - for near static mode such does not matter - as does not and the initial ON-spike

TL431 Test

. . . THIS -- the TEST Z-up -- a random improvisational voltage regulator . . .

what we got ::

what it is -- is derivates of TL431 for lower start-up voltages /!\ not fully tested /!\ nor built in practice

/!\ -- i compacted the schematics . . . so i hope it's what'ey R
