Description for the TL431

The TL431LI /TL432LI are pin-to-pin alternatives to TL431 / TL432.TL43xLI offers better stability, lower temperature drift (VI(dev)), andlower reference current (Iref) for improved systemaccuracy.

The TL431 and TL432 devices are three-terminal adjustable shunt regulators, withspecified thermal stability over applicable automotive, commercial, and military temperatureranges. The output voltage can be set to any value between Vref(approximately
2.5 V) and 36 V, with two external resistors. These devices have a typical output impedanceof 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making thesedevices excellent replacements for Zener diodes in many applications, such as onboard regulation,adjustable power supplies, and switching power supplies. The TL432 device has exactly the samefunctionality and electrical specifications as the TL431 device, but has different pinouts for theDBV, DBZ, and PK packages.

Both the TL431 and TL432 devices are offered in three grades, with initial tolerances (at25°C) of 0.5%, 1%, and 2%, for the B, A, and standard grade, respectively. In addition, low outputdrift versus temperature ensures good stability over the entire temperature range.

The TL43xxC devices are characterized for operation from 0°C to 70°C, the TL43xxI devicesare characterized for operation from –40°C to 85°C, and the TL43xxQ devices are characterized foroperation from –40°C to 125°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
