Product Summary

The TL431C is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature range. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors (see Figure 17). The TL431C have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.

Parametrics

TL431C absolute maximum ratings: (1)Cathode voltage, VKA (see Note 1): 37 V; (2)Continuous cathode current range, IKA: −100 mA to 150 mA; (3)Reference input current range: −50 μA to 10 mA; (4)Operating virtual junction temperature, TJ: 150°C; (5)Storage temperature range, Tstg: −65°C to 150°C.

Features
