ATL431BQDBZR TI Voltage Reference
The ATL431BQDBZR is a low-IQ adjustable precision shunt regulator from Texas Instruments in SOT-23-3 package . For selection, verify output voltage adjustable from 2.5 V to 36 V using two external resistors, reference voltage of 2.5 V with ±0.5% tolerance (B grade), cathode current from 35 µA to 15 mA, typical output impedance of 0.3 Ω, and operating temperature from -40°C to +125°C . Features include ultra-low cathode current for power-sensitive designs, excellent thermal stability, and low dynamic output impedance. Ideal for low-power SMPS feedback circuits, precision voltage references for ADCs/DACs, shunt regulators replacing zener diodes, overvoltage protection, and constant current sources/sinks in portable battery-powered equipment .
