• Mphamvu yamagetsi yolozera pa 25°C
- 0.5% (B kalasi)
- 1% (giredi A)
- 2% (Standard giredi)
• Mphamvu yotulutsa yosinthika: Vref mpaka 36 V
• Kugwiritsa ntchito kuyambira -40°C mpaka 125°C
• Kutsika kwa kutentha (TL43xB)
- 6 mV (C kutentha)
- 14 mV (I temp, Q temp)
• Phokoso Lochepa Lotulutsa
• 0.2-Ω Kulepheretsa komwe kumatulutsa

TL431LI / TL432LI ndi njira zina zapin-to-pini
ku TL431/TL432.TL43xLI imapereka bata bwino,
Kutsika kwa kutentha (VI(dev)), ndi kutsika
Reference current (Iref) ya kachitidwe kabwino
kulondola.
Zida za TL431 ndi TL432 zili ndi ma terminal atatu
owongolera ma shunt osinthika, okhala ndi matenthedwe odziwika
kukhazikika pamagalimoto oyenera, malonda, ndi
magulu ankhondo kutentha.Mphamvu yamagetsi imatha
kukhazikitsidwa ku mtengo uliwonse pakati pa Vref (pafupifupi
2.5 V) ndi 36 V, okhala ndi zopinga ziwiri zakunja.
Zida izi zimakhala ndi vuto losakwanira
pa 0.2g.Active linanena bungwe circuitry amapereka kwambiri
mawonekedwe akuthwa kuyatsa, kupanga zida izi
m'malo mwa Zener diode ambiri
ntchito, monga onboard regulation, chosinthika
magetsi, ndi kusintha magetsi.The
TL432 chipangizo ali chimodzimodzi magwiridwe antchito ndi
mafotokozedwe amagetsi monga chipangizo cha TL431, koma ali
ma pinouts osiyanasiyana a DBV, DBZ, ndi PK phukusi.
Zida zonse za TL431 ndi TL432 zimaperekedwa mkati
magiredi atatu, ndi kulolerana koyamba (pa 25°C) wa
0.5%, 1%, ndi 2%, ya B, A, ndi muyezo
kalasi, motero.Komanso, otsika linanena bungwe amakankhira motsutsana
kutentha kumatsimikizira bata bwino lonse
kutentha osiyanasiyana.
Zida za TL43xxC ndizodziwika kuti zizigwira ntchito
kuyambira 0 ° C mpaka 70 ° C, zida za TL43xxI zili
yodziwika ntchito kuchokera -40 ° C mpaka 85 ° C, ndi
zida za TL43xxQ ndizodziwika kuti zizigwira ntchito
kuchokera -40 ° C mpaka 125 ° C.
