- **Package:** TO-263 (D2PAK)  
- **Regulation Type:** Buck (Step-Down)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2673S-ADJ is a monolithic high-efficiency switching regulator designed for step-down (buck) applications. It integrates a power MOSFET switch and requires minimal external components. The adjustable version allows users to set the output voltage via an external resistor divider.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 5 external components  
- Internal soft-start reduces inrush current  
- Low standby current (50 µA typical in shutdown mode)  
- High efficiency over a wide load range  
- Available in a thermally enhanced D2PAK package  

This information is based on the manufacturer's datasheet and specifications.
