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. The TL1431C TL1431C is characterized for operation over the commercial temperature range of 0°C to 70°C. The TL1431Q TL1431Q is characterized for operation over the full automotive temperature range of -40°C to 125°C. The TL1431M TL1431M is characterized for operation over the full military temperature range of -55°C to 125°C.
