### **Descriptions:**  
The LM4040BIX3-2.1 is a high-precision, low-power shunt voltage reference that provides a stable 2.1V output. It is designed for applications requiring tight voltage accuracy and low temperature drift.  

### **Features:**  
- **High Accuracy:** ±0.1% initial tolerance  
- **Low Noise:** Low output noise performance  
- **Wide Operating Current:** 60µA to 15mA  
- **Small Form Factor:** SOT-23 package for space-constrained designs  
- **No Output Capacitor Required:** Stable without external compensation  
- **Reverse Breakdown Protection:** Protects against accidental reverse bias  

This device is commonly used in precision analog circuits, data converters, power supplies, and battery-powered systems.
