Description and Introduction

3-terminal 1A positive voltage regulatir. Peak output current 1.8A(typ). Output voltage 18V(typ). The LM7818 is a positive voltage regulator manufactured by WST (Wing Shing Computer Components). 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:** 21V to 35V (recommended for stable regulation)  
- **Dropout Voltage:** ~2V (minimum input-output differential)  
- **Line Regulation:** 0.03% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package Type:** TO-220 (standard)  

### **Descriptions:**  
- The LM7818 is a three-terminal linear voltage regulator designed to provide a stable +18V DC output.  
- It includes built-in thermal overload protection, short-circuit protection, and safe operating area (SOA) protection.  
- Suitable for applications requiring fixed, regulated voltage with minimal external components.  

### **Features:**  
- **Fixed Output Voltage:** +18V ±4% tolerance.  
- **Thermal Protection:** Shuts down automatically if overheating occurs.  
- **Short-Circuit Protection:** Safeguards against excessive current.  
- **No External Components Required:** Only input/output capacitors are recommended for stability.  
- **Wide Input Voltage Range:** Supports up to 35V input.  

This information is strictly factual from Ic-phoenix technical data files.
