Description and Introduction

Low-Voltage Adjustable Precision Shunt Regulator The TLV431BCDBZR 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 Cathode Current Range:** 100µA to 70mA  
- **Low Operating Current:** 80µA (typical)  
- **Output Voltage Tolerance:** ±0.5% (B grade), ±1% (A grade)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
- The TLV431BCDBZR is a three-terminal adjustable shunt regulator with thermal stability.  
- It is designed for low-voltage applications and provides precise voltage regulation.  
- It can replace traditional Zener diodes with improved accuracy and lower dynamic impedance.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Low Reference Voltage (1.24V)** for low-voltage applications  
- **Low Dynamic Output Impedance (0.2Ω typical)**  
- **Wide Operating Cathode Current Range (100µA to 70mA)**  
- **Low Temperature Coefficient** for stable performance  
- **Available in SOT-23 Package** for space-constrained designs  

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