Description and Introduction

Micropower Voltage Reference Diode The **LM285BYZ-1.2** is a precision voltage reference manufactured by **NS (National Semiconductor)**. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.2V  
- **Tolerance:** ±1%  
- **Operating Current Range:** 10µA to 20mA  
- **Temperature Coefficient (Tempco):** 30ppm/°C (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92 (3-pin)  
- **Long-Term Stability:** 20ppm/1000hrs (typical)  
- **Line Regulation:** 0.2mV/mA (typical)  
- **Load Regulation:** 0.2Ω (typical)  

### **Descriptions:**  
- The LM285BYZ-1.2 is a **low-power, precision shunt voltage reference** designed for applications requiring stable voltage references.  
- It operates as a **two-terminal device**, functioning similarly to a Zener diode but with better accuracy and lower power consumption.  
- Suitable for **battery-powered systems, ADCs, DACs, and voltage regulators** due to its low quiescent current.  

### **Features:**  
- **Low Power Consumption:** Operates down to **10µA**.  
- **High Accuracy:** ±1% initial tolerance.  
- **Stable Over Temperature:** Low temperature coefficient (30ppm/°C).  
- **Wide Operating Range:** Works from **-40°C to +85°C**.  
- **No External Components Required:** Simple two-terminal operation.  
- **Long-Term Stability:** Maintains performance over time (20ppm/1000hrs).  

This part is commonly used in precision analog circuits where a stable voltage reference is critical.
