(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION

The TL1431 is a precision programmable reference with specified thermal stability over the automotive

temperature range. The output voltage can be set to any value between V_I(ref)(approximately 2.5 V) and 36 V

with two external resistors (see Figure 16). 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.
