- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The LM22671MR-ADJ/NOPB is a step-down (buck) switching regulator with an adjustable output voltage. It integrates a high-side N-channel MOSFET and is designed for high efficiency and compact power supply solutions.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 42V operation.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **High Efficiency:** Up to 91% efficiency with integrated MOSFET.  
- **Thermal Shutdown & Current Limit:** Protects against overloads and overheating.  
- **Frequency Synchronization:** Allows synchronization with an external clock.  
- **Low Quiescent Current:** 3.5 mA typical for improved light-load efficiency.  
- **Soft-Start:** Reduces inrush current during startup.  

This regulator is suitable for industrial, automotive, and general-purpose power supply applications.
