TL431AQDBZRQ1 Description

Short technical summary and product information.

The TL431AQDBZRQ1 from Texas Instruments is a three-pin adjustable shunt regulator designed for automotive applications. It is qualified for AEC-Q100 test guidance and operates within an ambient temperature range of -40°C to 125°C.

 

This device allows for an adjustable output voltage from VREF (approximately 2.5V) up to 36V, set using two external resistors. Key electrical characteristics include a typical output impedance of 0.2 Ω, a sink-current capability ranging from 1 mA to 100 mA, and a typical temperature drift of 14 mV (Q Temp). The reference voltage tolerance at 25°C is 1% for the A Grade.

 

The TL431AQDBZRQ1 features active output circuitry for a sharp turn-on characteristic, making it a suitable replacement for Zener diodes in applications such as onboard regulation, adjustable power supplies, and switching power supplies. It is supplied in a SOT-23 package suitable for surface mounting.

 

Quality information indicates RoHS3 compliance and REACH unaffected status, with an MSL rating of Level 1. The standard package quantity is 3,000 units on tape and reel.
