Iyo TL431LI / TL432LI ipini-kupini dzimwe nzira dzeTL431 / TL432.TL43xLI inopa kugadzikana kuri nani, yakadzika tembiricha yekudonha (VI (dev)), uye yakaderera referensi ikozvino (Iref) yekuvandudza sisitimu.
Iyo TL431 uye TL432 zvishandiso zvitatu-terminal inogadziriswa shunt regulators, ine yakatsanangurwa kugadzikana kwemafuta pamusoro peanoshanda emotokari, yekutengesa, uye mauto tembiricha.Mhepo inobuda inogona kuiswa kune chero kukosha pakati peVref (inenge 2.5 V) uye 36 V, ine maviri ekunze anopikisa.Midziyo iyi ine yakajairwa kubuda impedance ye 0.2 Ω.Active output circuitry inopa yakanyanya kupinza-on hunhu, ichiita kuti midziyo iyi itsive yakanakisa yeZener diodes mune akawanda maapplication, senge onboard regulation, inogadzirika magetsi, uye switching magetsi emagetsi.Mudziyo weTL432 une mashandiro akafanana nemagetsi seTL431 mudziyo, asi une mapinipu akasiyana eDBV, DBZ, uye PK mapakeji.
