Description and Introduction

Precision Micropower Shunt Voltage Reference The LM4040EEM3X-3.0 is a precision voltage reference manufactured by NS (National Semiconductor). Below are the key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 3.0V  
- **Initial Accuracy:** ±0.1% (A grade)  
- **Temperature Coefficient:** 50 ppm/°C (typical)  
- **Operating Current Range:** 60 µA to 15 mA  
- **Output Voltage Tolerance:** ±0.1%, ±0.2%, ±0.5%, ±1% (depending on grade)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +85°C  
- **Long-Term Stability:** 20 ppm/1000 hours (typical)  

### **Descriptions:**  
- The LM4040 is a precision two-terminal shunt voltage reference.  
- It provides a fixed output voltage with high accuracy and low temperature drift.  
- Available in multiple voltage options (1.225V to 5.0V).  
- Designed for space-constrained applications due to its small SOT-23 package.  

### **Features:**  
- **Low Dropout Operation:** Works with minimal headroom voltage.  
- **Low Noise:** Ensures stable voltage output for precision applications.  
- **Wide Operating Current Range:** 60 µA to 15 mA.  
- **No External Capacitor Required:** Stable without additional components.  
- **AEC-Q100 Qualified:** Suitable for automotive applications.  
- **Reverse Breakdown Protection:** Enhances reliability in circuit designs.  

This device is commonly used in precision power supplies, data converters, and battery-powered systems requiring stable voltage references.
