TLVH431AQDBZR TI Shunt Voltage Reference | SOT-23-3 | 1.24V-18V, 0.5% Accuracy

Product Overview

The TLVH431AQDBZR from Texas Instruments is a low-voltage, adjustable precision shunt voltage reference in a compact SOT-23-3 package. It offers a wide output voltage range from 1.24V to 18V with an initial accuracy of 0.5% (A-grade). The device features low dynamic impedance (0.25Ω typical) and fast turn-on response, making it ideal for power supply regulation, data acquisition systems, and automotive electronics. Operating over a temperature range of -40°C to +125°C, it ensures reliable performance in harsh environments.
