TL431BQDBZR Description

Short technical summary and product information.

The TL431BQDBZR from Texas Instruments is a three-terminal adjustable shunt regulator designed for stable operation over automotive, commercial, and military temperature ranges. Its output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors. This device features a typical output impedance of 0.2Ω and a sink current capability ranging from 1mA to 100mA.

 

With a reference voltage tolerance of 0.5% at 25°C (B grade), the TL431BQDBZR ensures accuracy in voltage regulation applications. It operates from -40°C to 125°C, making it suitable for demanding environments. The device is housed in a compact SOT-23 package, ideal for space-constrained designs.

 

This shunt regulator is an excellent replacement for Zener diodes in various applications, including on-board regulation and adjustable power supplies. Its active output circuitry provides a sharp turn-on characteristic, enhancing its performance and reliability.
