TLVH431BQDBZT TI Shunt Voltage Reference | SOT-23-3 | 1.24V, 0.5% Accuracy

Product Overview

The TLVH431BQDBZT is a low-voltage, precision adjustable shunt voltage reference from Texas Instruments. It operates with a typical reference voltage of 1.24 V and offers a tight output tolerance of 0.5% (B grade). The device is designed for space-constrained applications, housed in a small SOT-23-3 package. It features a wide cathode voltage range from Vref to 18 V, low dynamic impedance of 0.25 Ω (typical), and a low output noise of 30 nV/√Hz. The TLVH431BQDBZT is ideal for precision voltage regulation, monitoring, and reference applications in industrial, automotive, and consumer electronics.
