Description and Introduction

Precision Micropower Shunt Voltage Reference The LM4051BIM3-1.2 is a precision voltage reference manufactured by NS (National Semiconductor).  

### **Specifications:**  
- **Output Voltage:** 1.2V  
- **Initial Accuracy:** ±0.1%  
- **Temperature Coefficient:** 20ppm/°C (typical)  
- **Operating Current:** 45µA (typical)  
- **Output Current:** 15mA (maximum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23 (3-pin)  

### **Descriptions:**  
- The LM4051BIM3-1.2 is a shunt voltage reference with a fixed output voltage of 1.2V.  
- It provides high accuracy and low temperature drift, making it suitable for precision applications.  
- The device operates without an external capacitor for stability but can be used with one for improved noise performance.  

### **Features:**  
- **Low Dropout Operation:** Works with minimal headroom voltage.  
- **Low Noise:** Suitable for noise-sensitive applications.  
- **Wide Operating Range:** Compatible with various supply voltages.  
- **Reverse Breakdown Protection:** Protects against reverse-bias conditions.  
- **Stable with Capacitive Loads:** No oscillation issues with or without an output capacitor.  

This device is commonly used in ADCs, DACs, power supplies, and other precision analog circuits.
