Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator The LM2575M-5.0 is a step-down (buck) switching voltage regulator manufactured by ON Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 5.0V (Fixed)  
- **Output Current:** Up to 1A  
- **Input Voltage Range:** 4.75V to 40V  
- **Switching Frequency:** 52 kHz  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown and current limit  

### **Descriptions:**  
The LM2575M-5.0 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed for easy implementation and requires minimal external components. The fixed 5.0V output version simplifies design while maintaining high efficiency.  

### **Features:**  
- Simple and easy-to-use buck regulator  
- Requires only 4 external components  
- Internal frequency compensation  
- Low power standby mode (IQ < 80μA)  
- High efficiency compared to linear regulators  
- Wide input voltage range  
- Thermal shutdown and current limit protection  
- Available in a TO-263 package for improved thermal performance  

This regulator is commonly used in power supply applications, battery chargers, and industrial systems.
