Product Summary
The TL4311 is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. The TL4311 has a typical output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making the TL4311 excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
