Description and Introduction

SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator The LM2597M-1.2 is a step-down (buck) switching voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 1.2V (fixed)  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 150 kHz  
- **Efficiency:** Up to 90%  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The LM2597M-1.2 is a monolithic integrated circuit that provides all the active functions for a step-down switching regulator.  
- It is designed to drive a 3A load with excellent line and load regulation.  
- Includes a fixed-frequency oscillator (150 kHz) and an internal feedback loop for stability.  
- Requires minimal external components for operation.  

### **Features:**  
- **Fixed 1.2V Output Voltage**  
- **3A Output Current Capability**  
- **Wide Input Voltage Range (4.5V to 40V)**  
- **Internal Frequency Compensation**  
- **Thermal Shutdown and Current Limit Protection**  
- **Low Power Standby Mode (IQ < 80μA)**  
- **Available in an 8-Pin SOIC Package**  

This information is strictly based on the manufacturer's datasheet and specifications.
