Description and Introduction

9-42V Wide Vin, 0.5A, Constant On-Time Non-Synchronous Buck Regulator 8-VSSOP -40 to 125 The LM25007MM is a switching regulator manufactured by National Semiconductor (NS). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 6V to 42V  
- **Output Voltage Range:** Adjustable from 1.225V to 37V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin VSSOP (MM)  

### **Descriptions:**  
The LM25007MM is a step-down (buck) switching regulator designed for high-voltage applications. It integrates a high-side N-channel MOSFET and provides a simple, efficient solution for DC-DC conversion. The device operates in a constant-frequency current-mode control architecture, ensuring stable performance across varying load conditions.  

### **Features:**  
- **Wide Input Voltage Range (6V to 42V)**  
- **Integrated 500mA N-Channel MOSFET**  
- **Adjustable Output Voltage (1.225V to 37V)**  
- **Programmable Switching Frequency (Up to 1MHz)**  
- **Current-Mode Control for Improved Stability**  
- **Thermal Shutdown Protection**  
- **Undervoltage Lockout (UVLO)**  
- **Low Quiescent Current (Typical 2.5mA)**  
- **Soft-Start Functionality**  

This information is based on the manufacturer's datasheet. For detailed performance characteristics and application circuits, refer to the official documentation.
