TL431BCDBZR TI Voltage References
The TL431BCDBZR is a three-terminal adjustable precision shunt regulator from Texas Instruments in 3-pin SOT-23 (DBZ) package, offering programmable output from 2.495V to 36V. For selection, verify cathode current from 1mA to 100mA, reference voltage of 2.495V with ±0.5% tolerance (B grade), typical output impedance of 0.2Ω, low output noise, excellent thermal stability, and operating temperature from -40°C to +125°C. Ideal for SMPS feedback circuits (opto-coupler drivers), precision voltage references for ADCs/DACs, shunt regulators replacing zener diodes, overvoltage protection, and constant current sources.
