TL431LI / TL432LI yog tus pin-to-pin lwm txoj rau TL431 / TL432.TL43xLI muaj kev ruaj ntseg zoo dua, qis qis dua (VI (dev)), thiab qis siv tam sim no (Iref) kom txhim kho qhov tseeb.
TL431 thiab TL432 cov khoom siv yog peb lub davhlau ya nyob twg adjustable shunt regulators, nrog rau cov thermal stability tshaj lub tsheb, kev lag luam, thiab tub rog kub ntau yam.Cov zis hluav taws xob tuaj yeem raug teeb tsa rau txhua tus nqi ntawm Vref (kwv yees li 2.5 V) thiab 36 V, nrog rau ob qho kev tawm tsam sab nraud.Cov khoom siv no muaj qhov tso tawm raug impedance ntawm 0.2 Ω.Active output circuitry muab tus cwj pwm zoo tig-raug, ua cov cuab yeej zoo hloov pauv rau Zener diodes hauv ntau daim ntawv thov, xws li kev tswj hwm onboard, kho cov khoom siv hluav taws xob, thiab hloov cov khoom siv hluav taws xob.Cov cuab yeej TL432 muaj qhov ua haujlwm zoo ib yam thiab cov khoom siv hluav taws xob raws li cov khoom siv TL431, tab sis muaj qhov sib txawv pinouts rau DBV, DBZ, thiab PK pob.
