Radiation-hardened, QML-V, 2.4V to 36V adjustable shunt voltage reference

The TL1431 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 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.

The TL1431 is characterized for

operation over the full military temperature range of –55°C to 125°C.
