Description and Introduction

1-A Simple Step-Down Switching Voltage Regulators The TL2575-33 is a step-down (buck) switching regulator manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **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 80%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package Type:** TO-220 (5-pin)  
- **Regulation Type:** PWM (Pulse Width Modulation)  

### **Descriptions:**
- The TL2575-33 is a monolithic integrated circuit that provides all active functions for a step-down switching regulator.  
- It is designed for simplicity and efficiency in converting higher DC input voltages to a lower regulated output voltage.  
- The device includes an internal oscillator, feedback control, and a high-current switch.  

### **Features:**
- **Fixed Output Voltage (3.3V)**  
- **Wide Input Voltage Range (4.75V to 40V)**  
- **High Efficiency (Up to 80%)**  
- **Internal Current Limiting & Thermal Shutdown**  
- **Low Standby Current (50 µA typical in shutdown mode)**  
- **Requires Minimal External Components**  
- **TO-220 Package for Easy Heat Dissipation**  

This information is based solely on the manufacturer's datasheet and technical documentation.
