- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  
- **Regulation Type:** Buck (Step-Down)  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**
The LM2575SX-12/NOPB is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed to drive a 1A load with excellent line and load regulation. The device requires minimal external components, simplifying power supply design.

### **Features:**
- **Fixed 12V Output Voltage**  
- **Wide Input Voltage Range (4.75V to 40V)**  
- **1A Output Current Capability**  
- **Internal Frequency Compensation**  
- **Low Power Standby Mode (50μA typical)**  
- **Thermal Shutdown and Current Limit Protection**  
- **Simple and Easy-to-Use Design**  
- **Available in a TO-263-5 Package**  

This regulator is commonly used in industrial, automotive, and consumer applications where efficient step-down voltage conversion is required.
