Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431CDBZR 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 Current (I_KA):** 80µA (typical)  
- **Sink Current Capability:** 1mA to 70mA  
- **Accuracy:** 0.5% (A-grade), 1% (B-grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- The TLVH431 is a low-voltage version of the TL431 shunt regulator.  
- It provides adjustable output voltage with high precision.  
- Designed for low-power applications requiring tight voltage regulation.  

### **Features:**  
- Low-voltage operation (down to 1.24V)  
- Low operating current (80µA typical)  
- Adjustable output voltage  
- Stable with low-ESR capacitors (≥0.47µF)  
- Available in A-grade (0.5%) and B-grade (1%) accuracy  
- Small SOT-23 package for space-constrained designs

Application Scenarios & Design Considerations

Low-Voltage Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5 --: Low-voltage adjustable shunt regulator with similar 1.24V reference and SOT-23 package, widely used as a TLVH431 substitute.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in the same SOT-23 package, though its 2.5V reference requires checking the lower-voltage application.
  • AZ431AN-B --: Adjustable shunt regulator in SOT-23 with comparable reference voltage and current capability, offering a cost-effective alternative.
