TL1431CDR Description

Short technical summary and product information.

The TL1431CDR from Texas Instruments is a precision adjustable (programmable) shunt voltage reference designed for stable thermal performance across various temperature ranges. Its output voltage can be precisely set between 2.5V and 36V using two external resistors, making it a versatile component for power supply regulation.

Key electrical characteristics include a low reference current, a 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 has a maximum temperature coefficient of 114ppm/°C. It operates reliably within an extended temperature range of -40°C to 125°C.

Available in multiple package options such as TSSOP-8, SOIC-8, and TO-92, the TL1431CDR is suitable for both surface mount and through-hole applications. Its active output circuitry provides a sharp turn-on characteristic, serving as an effective replacement for Zener diodes in many designs. This makes it an excellent choice for applications requiring accurate and stable voltage references.
