TL431LI / TL432LI ni pin-to-pin ubundi buryo bwa TL431 / TL432.TL43xLI itanga ituze ryiza, ubushyuhe bwo hasi (VI (dev)), hamwe nibisobanuro biri hasi (Iref) kugirango sisitemu ibe nziza.
Ibikoresho bya TL431 na TL432 nuburyo butatu bushobora guhindurwa shunt, hamwe nubushyuhe bwihariye bwumuriro hejuru yubushyuhe bwimodoka, ubucuruzi, nubusirikare.Ibisohoka voltage irashobora gushirwa kubiciro byose hagati ya Vref (hafi 2,5 V) na 36 V, hamwe na rezo ebyiri zo hanze.Ibi bikoresho bifite ibyasohotse mubisanzwe 0.2 Ω.Ibikorwa bisohoka byumuzunguruko bitanga uburyo bukomeye bwo gufungura ibintu, bigatuma ibyo bikoresho bisimburwa neza na diode ya Zener mubisabwa byinshi, nko kugenzura ubwato, gutanga amashanyarazi, no guhindura amashanyarazi.Igikoresho cya TL432 gifite imikorere imwe nuburyo bwihariye bwamashanyarazi nkigikoresho cya TL431, ariko gifite pinout zitandukanye kubikoresho bya DBV, DBZ, na PK.
