TL431AQDBVR Description

Short technical summary and product information.

The TL431AQDBVR from Texas Instruments is a three-terminal adjustable shunt regulator designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between approximately 2.5V (Vref) and 36V using two external resistors. This device features a typical output impedance of 0.2 Ohms and an active output circuitry that provides a sharp turn-on characteristic.

With a sink current capability ranging from 1 mA to 100 mA and a temperature coefficient of 30 ppm/°C, the TL431AQDBVR is suitable for applications requiring stable voltage references. It operates within a temperature range of -40°C to 125°C.

The TL431AQDBVR is housed in a SOT-23-5 surface-mount package, making it a versatile component for on-board regulation, adjustable power supplies, and switching power supplies. It serves as an excellent replacement for Zener diodes in many circuit designs.

This component is RoHS3 compliant, has an MSL of 1, and is REACH unaffected. Its adjustable nature and precise regulation make it a valuable part for power management circuits.
