- **Internal Short-Circuit Protection:** Yes  
- **Package Type:** TO-220  

### **Descriptions:**  
- The KA7808 is a three-terminal fixed positive voltage regulator designed to provide a stable +8V DC output.  
- It is part of the 78xx series of linear regulators and is commonly used in power supply circuits.  
- The regulator includes built-in thermal shutdown and current limiting for protection against excessive power dissipation.  

### **Features:**  
- Fixed +8V output voltage  
- High ripple rejection  
- Low output noise  
- No external components required for basic operation (except for input/output capacitors)  
- Robust thermal and short-circuit protection  

This information is based on Fairchild Semiconductor's documentation for the KA7808 regulator.
