Description and Introduction

Adjustable Micropower Voltage Reference The LM185 is a precision voltage reference manufactured by **Intersil** (now part of **Renesas Electronics**). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.235V, 2.5V, 5V, or 10V (depending on variant)  
- **Operating Current Range:** 10µA to 20mA  
- **Initial Accuracy:** ±0.5% (typical)  
- **Temperature Coefficient:** 20ppm/°C (typical)  
- **Long-Term Stability:** 20ppm/1000hr (typical)  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade)  
- **Package Options:** TO-92, SOIC-8, PDIP-8  

### **Descriptions:**
- The **LM185** is a low-power, two-terminal shunt voltage reference.  
- It is designed for precision applications requiring stable voltage references.  
- Available in multiple fixed output voltages (e.g., 1.235V, 2.5V, 5V, 10V).  
- Operates over a wide current range, making it suitable for battery-powered systems.  

### **Features:**
- **Low Power Consumption:** Operates down to **10µA**.  
- **High Accuracy:** Tight initial tolerance (±0.5%).  
- **Low Temperature Drift:** 20ppm/°C ensures stability across temperature.  
- **Wide Operating Range:** Works from **-40°C to +85°C**.  
- **Two-Terminal Shunt Configuration:** Easy to implement in circuits.  
- **Long-Term Stability:** Minimal drift over time (20ppm/1000hr).  

The **LM185** is commonly used in **ADCs, DACs, power supplies, and battery management systems** where a stable voltage reference is critical.
