### **Descriptions:**  
The TL431AQDBVT is a precision voltage reference with an adjustable output, commonly used in switching power supplies, voltage monitoring, and error amplifiers. It provides stable voltage regulation by comparing an internal reference with an external voltage divider.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low dynamic output impedance (0.2Ω typical)  
- Low output noise voltage  
- Wide operating current range (1mA to 100mA)  
- Sink current capability up to 100mA  
- Automotive-grade (AEC-Q100 qualified)  
- Available in a small SOT-23-5 package  

This device is widely used in power management, battery chargers, and voltage regulation applications.
