Description and Introduction

SIMPLE SWITCHER 3A Step-Down Voltage Regulator with Adjustable Current Limit The LM2673SX-5.0 is a switching voltage regulator manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Fixed 5.0V  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 260 kHz  
- **Efficiency:** Up to 92%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Regulation Type:** Buck (Step-Down)  

### **Descriptions:**
The LM2673SX-5.0 is a monolithic integrated circuit designed for step-down (buck) voltage regulation. It provides a fixed 5.0V output with high efficiency and requires minimal external components. The device is suitable for a wide range of applications, including power supplies for industrial, automotive, and consumer electronics.

### **Features:**
- **Simple and Easy-to-Use Design**  
- **High Efficiency (up to 92%)**  
- **3A Output Current Capability**  
- **Wide Input Voltage Range (8V to 40V)**  
- **Internal Soft-Start Function**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  
- **Low Power Standby Mode**  
- **Requires Few External Components**  

This regulator is ideal for applications requiring a stable 5V supply from higher input voltages with high efficiency and reliability.
