Description and Introduction

Precision Micropower Shunt Voltage Reference The LM4051AEM3X-1.2 is a precision voltage reference manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 1.2V  
- **Tolerance:** ±0.1% (A-grade)  
- **Temperature Coefficient:** 20 ppm/°C (typical)  
- **Operating Current Range:** 45 µA to 15 mA  
- **Output Current:** Up to 15 mA  
- **Line Regulation:** 0.05 mV/V (typical)  
- **Load Regulation:** 0.1 mV/mA (typical)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The LM4051AEM3X-1.2 is a shunt-mode voltage reference, meaning it requires an external resistor to set the operating current.  
- It provides a stable 1.2V output with high accuracy and low noise.  
- Designed for precision applications such as data converters, power supplies, and instrumentation.  

### **Features:**  
- **Low Dropout Operation:** Works with very low headroom voltage.  
- **Low Noise:** Suitable for high-precision analog circuits.  
- **Wide Operating Current Range:** Supports flexibility in design.  
- **Reverse Breakdown Protection:** Enhances device reliability.  
- **Small Form Factor:** SOT-23-3 package for space-constrained applications.  

This device is ideal for applications requiring a stable, low-noise voltage reference with high accuracy.
