(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.
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 VI(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
. 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.
