Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLV431BQDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Cathode Current Range:** 100µA to 70mA  
- **Low Operating Current:** 80µA (typical)  
- **Accuracy:** 0.5%, 1%, and 2% options  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TLV431BQDBVR is a three-terminal adjustable shunt regulator with thermal stability and low output impedance. It is designed for applications requiring precision voltage references and regulation.  

### **Features:**  
- Adjustable output voltage  
- Low-voltage operation (down to 1.24V)  
- Low dynamic output impedance (0.25Ω typical)  
- Stable with low-ESR capacitors  
- Wide operating temperature range  
- Available in multiple accuracy grades  

This device is commonly used in power management, voltage monitoring, and precision regulation circuits.

Application Scenarios & Design Considerations

Low-Voltage Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5/NOPB --: Adjustable shunt regulator with similar 1.24V reference and low-voltage operation, pin-compatible function in SOT-23-5, widely available and often used as a TLV431 substitute.
  • AZ431AN-BTRE1 --: Adjustable precision shunt regulator with 2.5V reference and low cathode current, suitable for many TLV431 applications where a slightly higher reference voltage is acceptable.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in SOT-23-3, very common and cost-effective; usable when the 2.5V reference and 3-pin package fit the design.
