### **Descriptions:**  
The LM340S-5.0 is a monolithic integrated circuit designed for use as a fixed-voltage regulator. It provides internal current limiting, thermal shutdown, and safe operating area protection, making it robust against overload conditions.  

### **Features:**  
- Thermal overload protection  
- Short-circuit protection  
- Internal current limiting  
- High ripple rejection  
- Low cost and easy to use  
- Available in a surface-mount package (TO-263)  

This regulator is commonly used in power supply applications requiring a stable 5V output.
