Description and Introduction

SIMPLE SWITCHER Power Converter 150 KHz 0.5A Step-Down Voltage Regulator The LM2594N-5.0 is a step-down (buck) switching voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** Fixed 5.0V  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Up to 0.5A  
- **Switching Frequency:** 150 kHz  
- **Efficiency:** Up to 80%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** 8-Pin DIP (Dual Inline Package)  
- **Regulation Type:** PWM (Pulse Width Modulation)  
- **Protection Features:** Thermal shutdown and current limit  

### **Descriptions:**  
The LM2594N-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 by eliminating the need for external feedback resistors.  

### **Features:**  
- **Fixed 5.0V Output**  
- **Wide Input Voltage Range (4.5V to 40V)**  
- **Low Power Standby Mode (IQ < 80μA)**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown Protection**  
- **Current Limiting Protection**  
- **Requires Only 4 External Components**  
- **Available in TO-220 and DIP Packages**  

This regulator is commonly used in power supply applications requiring efficient step-down conversion with a stable 5V output.
