- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
The LM2576S-ADJ is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed for easy implementation 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 Design:** Requires few external components.  
- **Fixed or Adjustable Output:** Available in fixed or adjustable versions.  
- **Internal Frequency Compensation:** Simplifies circuit design.  
- **Thermal Shutdown and Current Limit Protection:** Enhances reliability.  
- **Low Power Standby Mode:** Reduces power consumption when disabled.  

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