Description and Introduction

SIMPLE SWITCHER? 40V, 500mA Low Component Count Step-Down Regulator 8-SOIC -40 to 125 The LM2674M-5.0/NOPB is a step-down voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 260 kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  
- **Regulation Type:** Buck (Step-Down) Converter  
- **Protection Features:** Thermal shutdown, current limiting  

### **Descriptions & Features:**  
- Simple and easy-to-use switching regulator with minimal external components.  
- Includes a fixed-frequency oscillator for stable operation.  
- Low dropout operation enhances efficiency.  
- Internal soft-start reduces inrush current.  
- Suitable for battery-powered and industrial applications.  
- Lead-free and RoHS-compliant (NOPB suffix).  

This regulator is commonly used in power supply designs requiring efficient step-down conversion from higher input voltages.
