Description and Introduction

LOW-VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS The TLV431IDBZRG4 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:** 80µA to 100mA  
- **Tolerance:** 0.5%, 1%, and 2% options  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- Adjustable output voltage with two external resistors  
- Low operational current (80µA minimum)  
- Stable with low-ESR capacitors (≥0.1µF)  
- Improved accuracy compared to the TL431  

### **Features:**  
- Low-voltage operation (down to 1.24V)  
- Low output noise  
- Fast turn-on response  
- Adjustable precision reference  
- Wide operating temperature range  

This device is commonly used in power supplies, battery chargers, and voltage monitoring applications.

Application Scenarios & Design Considerations

LOW-VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS

Alternative Part Number

  • LMV431AIM5 --: Adjustable shunt regulator with 1.24V reference in SOT-23-5, functionally equivalent to TLV431 and widely available.
  • AZ431AN-B --: Adjustable precision shunt regulator with similar 1.24V reference and SOT-23 package, suitable drop-in replacement.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in SOT-23, same package family and compatible regulation behavior though with 2.5V reference.
