Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLVH431AILPR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual data from Ic-phoenix technical data files:

### **Specifications:**  
- **Reference Voltage (Vref):** 1.24V (typical)  
- **Adjustable Output Voltage Range:** 1.24V to 6V  
- **Operating Cathode Current (IK):** 80µA (min) to 100mA (max)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Temperature Stability:** ±4mV (over full temperature range)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- The TLVH431AILPR is a low-voltage, three-terminal adjustable shunt regulator with thermal stability.  
- It is designed for applications requiring precision voltage references or adjustable regulation.  
- It can replace the TL431 in low-voltage applications (down to 1.24V).  

### **Features:**  
- **Low Voltage Operation:** Adjustable down to 1.24V.  
- **Low Operating Current:** As low as 80µA.  
- **High Accuracy:** Reference voltage tolerance of ±1.5%.  
- **Wide Operating Temperature Range:** -40°C to +125°C.  
- **Small Package:** Available in a space-saving SOT-23-3 package.  
- **Improved Stability:** Low output impedance for better transient response.  

This information is based on TI's official datasheet and product documentation.

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 tolerance grade, direct functional replacement in SOT-23 package.
  • TL431AILP --: Industry-standard adjustable shunt regulator with same TO-92 package and pinout, wider availability though higher minimum cathode voltage.
  • AZ431AN-ATRE1 --: Adjustable shunt regulator with comparable reference voltage and tolerance, suitable alternative from a different series and vendor.
