TL1431QD Description

Short technical summary and product information.

The TL1431QD from Texas Instruments is a precision programmable shunt reference designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between approximately 2.5V and 36V using two external resistors, making it highly versatile for applications requiring adjustable voltage regulation.

 

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 ranging from 1mA to 100mA and features low reference current consumption. This makes it an excellent replacement for Zener diodes in applications such as onboard regulation, adjustable power supplies, and switching power supplies.

 

The TL1431QD is supplied in an 8-pin SOIC package suitable for surface mounting. It operates within a wide temperature range of -40°C to 125°C, ensuring reliability in demanding environments. The device is RoHS compliant and meets REACH Unaffected status.
