TL431CD TI Adjustable Precision Shunt Regulator | 8-SOIC | 2.495V Ref, 0.5% Accuracy

Product Overview

The TL431CD from Texas Instruments is a three-terminal adjustable precision shunt regulator with a guaranteed temperature stability over the entire industrial temperature range. The output voltage can be set to any value between Vref (approximately 2.495 V) and 36 V with two external resistors. This device features a typical output impedance of 0.2 Ω and a typical output noise of 20 nV/√Hz. The TL431CD is offered in an 8-pin SOIC package, making it suitable for space-constrained applications.
