ATL431BQDBZR TI adjustable shunt regulator
The ATL431BQDBZR is a three-terminal low-IQ adjustable precision shunt regulator developed by Texas Instruments, supplied in tape-and-reel SOT-23-3 DBZ surface-mount package. This B-grade reference delivers 2.495 V internal reference voltage with ±0.5% initial accuracy, supporting programmable output voltage ranging from 2.5 V up to 36 V via external resistor divider networks, operating over a wide temperature range of -40 °C to 125 °C. Compared with conventional TL431 devices, it features drastically reduced minimum cathode regulation current and reference input current, making it suitable for low-power feedback loops, and the RoHS-compliant compact package minimizes PCB footprint for power supply and analog signal conditioning circuits.
The ATL431BQDBZR serves as a core feedback component for isolated and non-isolated SMPS flyback, buck and boost converters, precision programmable voltage reference circuits, constant current LED driver control loops, industrial sensor signal conditioning, battery monitoring systems, portable test instruments and embedded analog front-end modules. Hardware designers select this low-IQ precision shunt regulator for power-sensitive equipment requiring accurate voltage feedback, especially space-limited consumer, industrial and IoT hardware where minimized quiescent power loss and stable low-load operation are critical performance targets.
Alternative shunt IC Models
● TL431BQDBZR (Texas Instruments): Pin-compatible classic adjustable shunt regulator with 0.5% reference tolerance, higher minimum cathode current and mature market availability as general-purpose second-source reference solution.
● AS431ANTR-G1 (Diodes Incorporated): SOT-23-3 precision adjustable shunt reference with 0.5% accuracy, supporting 2.5 V to 36 V output for cost-sensitive power supply feedback circuits.
● LM431BIM3X/NOPB (onsemi): Three-terminal programmable shunt regulator offering wide voltage adjustment range and robust load driving capability for industrial analog control applications.
● ATL431AQDBZR (Texas Instruments): Same package low-IQ shunt regulator with 1% reference accuracy, a cost-down variant for projects relaxing precision requirements while retaining low quiescent current advantages.
