TL432AQPKG3 Description
The TL431LI / TL432LI are pin-to-pin alternativesto TL431 / TL432. TL43xLI offers better stability, lower temperature drift (VI(dev)), and lowerreference current (Iref) for improved systemaccuracy.The TL431 and TL432 devices are three-terminaladjustable shunt regulators, with specified thermalstability over applicable automotive, commercial, andmilitary temperature ranges. The output voltage canbe set to any value between Vref (approximately2.5 V) and 36 V, with two external resistors.These devices have a typical output impedanceof 0.2 Ω. Active output circuitry provides a verysharp turn-on characteristic, making these devicesexcellent replacements for Zener diodes in manyapplications, such as onboard regulation, adjustablepower supplies, and switching power supplies. TheTL432 device has exactly the same functionality andelectrical specifications as the TL431 device, but hasdifferent pinouts for the DBV, DBZ, and PK packages.
