Description and Introduction

5-V Precision Micropower Shunt Voltage Reference, 0.2% accuracy The LM4040B50IDBZT is a precision voltage reference manufactured by Texas Instruments.  

### **Specifications:**  
- **Output Voltage:** 2.5V (Note: The part number suggests "50" for 5.0V, but LM4040B50 is actually a 5.0V reference. Verify datasheet for exact variant.)  
- **Tolerance:** ±0.1% (B-grade)  
- **Temperature Coefficient:** 50 ppm/°C (typical)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Package:** SOT-23 (DBZ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Long-Term Stability:** 20 ppm/1000 hrs (typical)  

### **Descriptions:**  
- The LM4040 is a precision two-terminal shunt voltage reference.  
- Available in fixed reverse breakdown voltages (e.g., 2.048V, 2.5V, 3V, 4.096V, 5V).  
- Low noise and low dynamic impedance.  
- No external capacitor required for stability.  

### **Features:**  
- **High Accuracy:** Tight tolerances (A-grade: ±0.1%, B-grade: ±0.2%).
