DESCRIPTION
The TL1431-DIE is a precision programmable reference. This device has a typical output impedance of 0.2 Ω.
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.

Processing is per the Texas Instruments space 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
