Description and Introduction

SIMPLE SWITCHER 1A Step-Down Voltage Regulator 5-TO-220 The LM2575T-ADJLF03 is a switching voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 4.75V to 40V  
- **Output Voltage Range:** Adjustable (1.23V to 37V)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 52 kHz (fixed)  
- **Efficiency:** Up to 88%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220-5 (through-hole)  
- **Regulation Type:** Buck (step-down) converter  

### **Descriptions:**  
The LM2575T-ADJLF03 is a monolithic integrated circuit that provides all active functions for a step-down (buck) switching regulator. It is designed for easy implementation and requires minimal external components. The adjustable version allows the output voltage to be set using external resistors.  

### **Features:**  
- Simple and easy-to-use design  
- Requires only 4 external components  
- Internal frequency compensation  
- Fixed-frequency oscillator  
- Thermal shutdown and current limit protection  
- Low power standby mode (IQ ≈ 50 µA)  
- TTL shutdown capability  

This regulator is widely used in power supply applications requiring efficient step-down conversion.
