Description and Introduction

EASY SWITCHERE? 1.0 A STEP-DOWN VOLTAGE REGULATOR The LM2575-3.3 is a step-down (buck) switching voltage regulator manufactured by **MIT (Microelectronics Technology Inc.)**.  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 4.75V to 40V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (typical)  
- **Efficiency:** Up to 88% (depending on conditions)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, TO-263 (D2PAK)  

### **Descriptions:**  
The LM2575-3.3 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.  

### **Features:**  
- **Fixed 3.3V output**  
- **Wide input voltage range (4.75V to 40V)**  
- **1A output current capability**  
- **Internal frequency compensation**  
- **Thermal shutdown and current limit protection**  
- **Low power standby mode (when disabled)**  
- **Simple and cost-effective design**  

This regulator is commonly used in power supply applications where a stable 3.3V output is required from a higher input voltage.
