TL1431U/EM General Description

Engineered for precision and stability, the TL1431U/EM is a programmable reference that maintains specified thermal stability across automotive, commercial, and military temperature ranges. By using external resistors, users can easily set the output voltage to any value between V_I(ref) and 36 V, providing the necessary flexibility for voltage regulation in various applications. With a typical output impedance of 0.2 Ω, this device ensures consistent and reliable performance. Its active output circuitry also delivers a sharp turn-on characteristic, making it an excellent alternative to Zener diodes and other reference types in applications such as onboard regulation, adjustable power supplies, and switching power supplies. With a temperature range of –55°C to 125°C, the TL1431U/EM is built to withstand extreme conditions, making it an ideal choice for military environments
