TL1431QDR Description

Short technical summary and product information.

The TL1431QDR is a precision programmable shunt reference from Texas Instruments, designed for stable thermal performance across various temperature ranges. Its output voltage is adjustable from 2.5V up to 36V using two external resistors, making it a versatile component for power supply regulation and voltage referencing.

Key electrical characteristics include a low typical output impedance of 0.2Ω and a fast turn-on time of 500ns. The device supports a sink current capability from 1mA to 100mA and requires a minimum regulation current of 450µA. The initial accuracy is specified at a maximum of 0.4%, and the temperature coefficient is 114ppm/°C.

Available in TSSOP-8, SOIC-8, and TO-92 packages, the TL1431QDR is suitable for surface mount applications. It operates within an automotive, commercial, and military temperature range of -40°C to 125°C. This device serves as an excellent replacement for Zener diodes in many applications requiring precise voltage regulation.
