Description and Introduction

SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator with Features The LM2671M-12 is a step-down voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 12V  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 260 kHz  
- **Efficiency:** Up to 90%  
- **Package:** 8-Pin SOIC  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions:**  
The LM2671M-12 is a monolithic high-efficiency switching regulator designed for step-down (buck) applications. It integrates a power switch and control circuitry, requiring minimal external components.  

### **Features:**  
- Simple and easy-to-use design  
- Low dropout operation  
- Internal soft-start  
- Adjustable output version available (LM2671M-ADJ)  
- Low standby current in shutdown mode  
- High efficiency for reduced power dissipation  

This regulator is commonly used in power supply applications requiring a stable 12V output from a higher input voltage.
