Description and Introduction

6.9V Precision Voltage Reference The LM129AH is a precision voltage reference manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 6.9V ±0.2%  
- **Temperature Coefficient:** 10 ppm/°C (typical)  
- **Operating Current:** 1.2 mA (typical)  
- **Line Regulation:** 0.001%/V (typical)  
- **Load Regulation:** 0.005%/mA (typical)  
- **Long-Term Stability:** 20 ppm/1000 hours  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** TO-46 metal can  

### **Descriptions:**  
- The LM129AH is a high-precision, low-drift voltage reference designed for applications requiring stable and accurate voltage sources.  
- It is a shunt-type (two-terminal) reference, meaning it requires an external resistor for proper operation.  
- The device is laser-trimmed to ensure tight initial accuracy and low temperature drift.  

### **Features:**  
- **High Precision:** ±0.2% initial voltage tolerance.  
- **Low Drift:** 10 ppm/°C typical temperature coefficient.  
- **Low Noise:** Suitable for precision analog circuits.  
- **Wide Operating Range:** Functions reliably across industrial and military temperature ranges.  
- **Stable Performance:** Excellent long-term stability (20 ppm/1000 hours).  

This information is strictly based on the manufacturer's datasheet and knowledge base entries for the LM129AH by NSC.
