Description and Introduction

Low Voltage Precision Adjustable Shunt Regulator The **TLV431BSNT1G** is a precision low-voltage adjustable shunt regulator manufactured by **ON Semiconductor**.  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Cathode Current Range:** 1mA to 100mA  
- **Low Operating Current:** 80µA (typical)  
- **Tolerance:** ±0.5%, ±1%, and ±1.5% (depending on variant)  
- **Temperature Stability:** 4mV (typical) over full temperature range  
- **Package:** SOT-23-3 (Small Outline Transistor)  

### **Descriptions:**  
- Adjustable precision shunt regulator  
- Low-voltage operation suitable for battery-powered applications  
- Improved accuracy and thermal stability compared to standard regulators

- **Pb-Free and RoHS Compliant**  

This device is commonly used in power management, voltage monitoring, and feedback control circuits.

Application Scenarios & Design Considerations

Low Voltage Precision Adjustable Shunt Regulator

Alternative Part Number

  • LMV431AIM5/NOPB --: Pin-compatible adjustable shunt reference in SOT-23-5 with similar 1.24V reference and 0.5% tolerance grade, widely available and a common drop-in for TLV431 designs.
  • AZ431AN-BTRE1 --: Adjustable shunt regulator in SOT-23 with comparable reference voltage and tolerance, offered as a cost-effective second source with similar electrical behavior.
  • AP431SAKTR-G1 --: SOT-23 adjustable shunt reference with low operating current and 0.5% grade, suitable as an alternative when TLV431 supply is constrained.
