TL431AIDR2G

Overview

The TL431AIDR2G is a three-terminal programmable shunt regulator diode from onsemi, housed in an SOIC-8 package. It operates as a low temperature coefficient zener, programmable from Vref to 36 V using two external resistors. The device features a wide operating current range of 1.0 mA to 100 mA and a typical dynamic impedance of 0.22 Ω. It exhibits a reference voltage tolerance of ±1% at 25 °C and an equivalent full-range temperature coefficient of 50 ppm/°C. The component supports an operating ambient temperature range from -40 °C to +85 °C.

Feature Summary

Programmable output voltage capability up to 36 V
Low dynamic output impedance for stable regulation
Temperature compensated operation across the rated range
Pb-Free, Halogen Free/BFR Free, and RoHS compliant construction

Applications

Digital voltmeters
Power supplies
Op amp circuitry

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm that the AI designation aligns with the required ±1% initial accuracy and the -40 °C to +85 °C operating temperature range for the target application environment.

Selection Notes

Select this component when a precision shunt regulator with ±1% tolerance is required. Ensure the design accommodates the 1.0 mA to 100 mA cathode current range. Verify stability requirements against load capacitance conditions using the provided boundary curves.

Part Context

This part belongs to the TL431A series of programmable precision references. It serves as a monolithic IC voltage reference replacement for traditional zener diodes in applications requiring higher accuracy and lower temperature drift.
