Description and Introduction

Micropower Voltage Reference Diode The LM385M-1.2 is a precision voltage reference manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.235V (fixed)  
- **Operating Current Range:** 10µA to 20mA  
- **Temperature Coefficient:** 20ppm/°C (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Initial Accuracy:** ±1% (LM385M-1.2)  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Line Regulation:** 0.2%/V (typical)  
- **Load Regulation:** 0.3%/mA (typical)  

### **Descriptions:**  
- The LM385M-1.2 is a low-power, adjustable shunt voltage reference diode.  
- It is designed for precision voltage reference applications in portable and battery-powered systems.  
- The device operates with a minimal current of 10µA, making it suitable for low-power designs.  

### **Features:**  
- **Low Power Consumption:** Operates down to 10µA.  
- **High Accuracy:** ±1% initial voltage tolerance.  
- **Low Temperature Drift:** 20ppm/°C ensures stable performance over temperature variations.  
- **Wide Operating Current Range:** 10µA to 20mA.  
- **Adjustable Output:** Can be adjusted with external resistors (though the LM385M-1.2 is fixed at 1.235V).  
- **Stable Operation:** Minimal sensitivity to line and load changes.  

This information is based on the manufacturer's datasheet for the LM385M-1.2 by NSC.
