TL431AQDBZR TI Shunt Voltage Reference | SOT-23-3 | 2.495V, 1% Accuracy

Product Overview

The TL431AQDBZR is a precision programmable shunt voltage reference from Texas Instruments (TI), offering a stable 2.495V reference voltage with 1% initial accuracy. Housed in a compact SOT-23-3 package, it is designed for applications requiring low dynamic impedance, fast turn-on response, and wide operating current range (1 mA to 100 mA). This device serves as a cost-effective alternative to Zener diodes in voltage regulation, monitoring, and feedback control circuits.
