Description and Introduction

3-Terminal 1A Positive Voltage Regulator The KA7818 is a positive voltage regulator manufactured by Fairchild Semiconductor. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** +18V (fixed)  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** Up to 35V (recommended to stay within limits for stability)  
- **Dropout Voltage:** Typically 2V (input must be at least 20V for stable 18V output)  
- **Line Regulation:** 0.01%/V (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package Type:** TO-220 (common for power regulators)  

### **Descriptions:**  
- The KA7818 is a monolithic linear voltage regulator designed to provide a fixed +18V output.  
- It includes built-in thermal overload protection, short-circuit protection, and safe operating area (SOA) protection.  
- Suitable for applications requiring stable and regulated +18V DC power.  

### **Features:**  
- Fixed +18V output with high accuracy  
- Internal thermal shutdown protection  
- Short-circuit current limiting  
- No external components required for basic operation (though input/output capacitors are recommended for stability)  
- Low cost and widely available
