### **Descriptions:**  
The UC2572DTRG4 is a step-down (buck) switching regulator designed for high-efficiency power conversion. It operates with a fixed 100kHz switching frequency and provides an adjustable output voltage based on external resistor configurations. It is suitable for a variety of applications requiring stable DC power from a higher input voltage source.

### **Features:**  
- **Wide Input Voltage Range (4.5V to 40V)** – Supports various power sources.  
- **Adjustable Output Voltage** – Configurable via external resistors.  
- **1.5A Output Current Capability** – Suitable for moderate power applications.  
- **Fixed 100kHz Switching Frequency** – Simplifies filtering and design.  
- **Built-in Overcurrent Protection** – Enhances reliability.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Low Dropout Operation** – Efficient even with small input-output differentials.  
- **SOIC-8 Package** – Compact and suitable for space-constrained designs.  

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