The TL1431 device is a precision programmable reference with specified thermal stability
over automotive, commercial, and military temperature ranges. The output voltage can be set to any
value between VI(ref) (approximately 2.5 V) and 36 V with two external
resistors. This device has a typical
output impedance of 0.2 Ω. Active output circuitry provides a 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.
The TL1431C is characterized for operation over the commercial temperature range of 0°C
to 70°C. The TL1431Q is characterized for operation over the full automotive temperature range of
–40°C to 125°C. The TL1431M is characterized for operation over the full military temperature range
of –55°C to 125°C.
