TL431LIAIDBZR Description

Short technical summary and product information.

The TL431LI device from Texas Instruments is a three-terminal adjustable shunt regulator designed for applications requiring precise voltage regulation. It features optimized reference current and deviation characteristics, making it suitable for high-accuracy designs.

 

The output voltage can be precisely set to any value between Vref (approximately 2.495 V) and 36 V using two external resistors. This device boasts a typical output impedance of 0.3 Ω and active output circuitry for sharp turn-on characteristics, serving as an excellent replacement for Zener diodes.

 

Key electrical specifications include a reference voltage tolerance of 0.5% at 25°C (B Grade) and a maximum temperature drift of 10 mV (C Temp). The sink-current capability ranges from 1 mA (min) to 15 mA (max), with a maximum reference input current of 0.4 µA.

 

Packaged in a SOT-23 (DBZ) package, the TL431LIAIDBZR operates within a temperature range of -40°C to 85°C. It is supplied in a large tape and reel with a standard package quantity of 3,000 units.
