### **Descriptions:**
The LM4040B82IDBZR is a shunt voltage reference with a fixed 2.048V output. It provides high accuracy and low temperature drift, making it suitable for precision applications. It operates without an external capacitor, ensuring stability.

### **Features:**
- **Precision Voltage Reference:** Tight tolerances (±0.1%)  
- **Low Temperature Drift:** 100ppm/°C (max)  
- **Wide Operating Range:** -40°C to +125°C  
- **No Output Capacitor Required:** Stable without external components  
- **Small Package:** SOT-23 for space-constrained designs  
- **Low Noise:** Suitable for sensitive analog circuits  
- **Reverse Breakdown Protection:** Enhanced reliability  

This device is commonly used in ADCs, DACs, power supplies, and battery-powered systems requiring stable voltage references.
