3 Description
The TL431-DIE is a three-terminal adjustable shunt
regulator. This device has a typical output
impedance. Active output circuitry provides a very
sharp turnon characteristic, making the device an
excellent replacement for Zener diodes and other
types of references in applications such as onboard
regulation, adjustable power supplies, and switching
power supplies.

(2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
