- Stable with low ESR capacitors (≥0.1µF)  
- Adjustable output voltage (1.24V to 6V)  
- High accuracy (0.5% for A-grade)  
- Small SOT-23-3 package  

This device is commonly used in power management, voltage references, and precision regulation applications.

Application Scenarios & Design Considerations

Low-Voltage Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5 --: Low-voltage adjustable shunt regulator in SOT-23-5 with similar 1.24V reference and tolerance grade, direct functional substitute from the same vendor.
  • AZ431AN-BTRE1 --: Adjustable precision shunt regulator with comparable reference voltage and SOT-23 package, widely used as a TLVH431 replacement in feedback circuits.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in the same SOT-23-3 package and tolerance class; slightly higher minimum cathode voltage but pin-compatible and readily available.
