Description and Introduction

Adjustable Precision Shunt Regulator The TL431BCDBZT is a programmable precision voltage reference manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 2.495V to 36V (adjustable)  
- **Reference Voltage (Vref):** 2.495V (typical)  
- **Output Current (Cathode):** 1mA to 100mA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Tolerance:** 0.5%, 1%, or 2% (depending on variant)  
- **Package:** SOT-23-3 (DBZ)  

### **Descriptions:**  
The TL431BCDBZT is a three-terminal adjustable shunt regulator with thermal stability and low output noise. It is commonly used in voltage regulation, switching power supplies, and precision voltage references.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low dynamic output impedance (0.2Ω typical)  
- Sink current capability of 1mA to 100mA  
- Low temperature drift  
- Wide operating temperature range  
- Available in multiple tolerance grades  

This device is widely used in power management, battery chargers, and feedback control circuits.
