### **Descriptions:**  
The LM2574DW-ADJR2G 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 the output voltage to be set using external resistors.  

### **Features:**  
- Simple and easy-to-use design  
- Requires few external components  
- Internal frequency compensation  
- Fixed-frequency oscillator  
- Low power standby mode  
- High efficiency  
- Wide input voltage range  
- Thermal shutdown and current limit protection  

This regulator is commonly used in power supply applications, battery chargers, and DC-DC converters.
