Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431BQDBVT 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:** Up to 20mA  
- **Accuracy:** ±1% (A-grade), ±0.5% (B-grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TLVH431BQDBVT is a low-voltage version of the TL431 shunt regulator, optimized for lower power consumption.  
- It provides a stable reference voltage with adjustable output via external resistors.  
- Suitable for precision voltage regulation in battery-powered and low-voltage applications.  

### **Features:**  
- **Low-voltage operation** (down to 1.24V)  
- **Low operating current** (80µA typical)  
- **Adjustable output voltage**  
- **High accuracy** (±0.5% for B-grade)  
- **Stable with capacitive loads**  
- **Wide temperature range** (-40°C to +125°C)  
- **Small SOT-23-5 package** for space-constrained designs  

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

Application Scenarios & Design Considerations

Low-Voltage Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431BIMF/NOPB --: Low-voltage adjustable shunt regulator in SOT-23-3 with similar 1.24V reference and tolerance grade, pin-compatible function in many designs.
  • AZ431BZ-ATRE1 --: Adjustable shunt regulator with 2.5V reference and tight tolerance, widely used as a cost-effective substitute in similar regulator circuits.
  • TL431BIDBZR --: Industry-standard adjustable shunt regulator in SOT-23-3, same package family and function, though with 2.5V reference instead of 1.24V.
