- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown and current limit  

### **Descriptions:**  
The LM2576TV-3.3 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator. It is designed to drive a 3A load with excellent line and load regulation.  

### **Features:**  
- Simple and easy-to-use design  
- Requires minimal external components  
- Internal frequency compensation  
- Fixed-frequency oscillator  
- Low power standby mode (IQ ~ 50 μA)  
- High efficiency compared to linear regulators  
- Wide input voltage range  

This regulator is commonly used in power supply applications for industrial, automotive, and consumer electronics.
