### **Descriptions:**  
The LM4040AIZ2.5 is a shunt voltage reference that provides a stable 2.5V output. It is designed for precision applications requiring tight voltage tolerance and low temperature drift.  

### **Features:**  
- **High Accuracy:** ±0.1% (A-grade)  
- **Low Temperature Drift:** 25 ppm/°C  
- **Low Output Noise:** 35 µV (typical)  
- **Wide Operating Current Range:** 60 µA to 15 mA  
- **No External Capacitor Required**  
- **Stable with Capacitive Loads**  
- **Available in TO-92 Package**  

This device is commonly used in data converters, power supplies, and industrial control systems where precise voltage references are critical.
