TL431BQDBZT Description

Short technical summary and product information.

The TL431BQDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments. This three-terminal device provides thermal stability over automotive, commercial, and military temperature ranges. The output voltage can be precisely set between Vref (approximately 2.5V) and 36V using two external resistors.

 

Key electrical specifications include a reference voltage tolerance of 0.5% at 25°C for the B grade, and a typical output impedance of 0.2Ω. The device operates from -40°C to 125°C, making it suitable for various environmental conditions. Its sink-current capability ranges from 1mA to 100mA.

 

The TL431BQDBZT is housed in a compact SOT-23 package with 3 pins, designed for surface mounting. This regulator serves as an excellent replacement for Zener diodes in applications requiring on-board regulation and adjustable voltage references.
