Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431IDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V (adjustable)  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Current (I_KA):** 80µA (typical)  
- **Sink Current Capability:** 1mA to 70mA  
- **Initial Accuracy:** 0.5% (A grade), 1% (B grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TLVH431IDBVR is a low-voltage version of the TL431 shunt regulator, designed for precision voltage reference and regulation applications. It provides stable voltage references with low operating current, making it suitable for battery-powered and low-power systems.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low operating current (80µA typical)  
- Wide operating temperature range (-40°C to +125°C)  
- Stable with low-ESR capacitors (≥0.47µF)  
- Available in A (0.5%) and B (1%) voltage tolerance grades  
- Small SOT-23-5 package for space-constrained designs  

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 --: Low-voltage adjustable shunt regulator in SOT-23-5 with similar 1.24V reference and tolerance, a common drop-in for TLVH431 in many designs.
  • AZ431AN-ATRE1 --: Adjustable shunt regulator with comparable reference voltage and SOT-23 package, widely used as a cost-effective substitute for TLVH431.
  • TL431AIDBZR --: Industry-standard adjustable shunt regulator in SOT-23, same family function with slightly higher minimum cathode voltage, suitable when 1.24V operation is not required.
