- **Long-Term Stability:** 20 ppm/1000 hours (typical)  

### **Descriptions:**  
- The LM4040 is a precision two-terminal shunt voltage reference.  
- It provides a fixed 2.048V output with low noise and high stability.  
- Designed for space-constrained applications due to its small SOT-23 package.  

### **Features:**  
- **Low Output Noise:** 35 µV (typical)  
- **Wide Operating Current Range:** 60 µA to 15 mA  
- **No External Capacitor Required** (stable without one)  
- **Reverse Breakdown Voltage Options:** 2.048V (LM4040BIM7-2.0)  
- **AEC-Q100 Qualified** for automotive applications (certain versions)  
- **Low Dynamic Impedance:** 0.5 Ω (typical)  

This device is commonly used in precision voltage regulation for ADCs, DACs, and power supply monitoring.
