Description and Introduction

400mA and 500mA Voltage Regulator The LM2937IMPX-2.5 is a low-dropout voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 0.5V (typical at full load)  
- **Input Voltage Range:** 4.75V to 26V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Descriptions:**
- The LM2937IMPX-2.5 is a low-dropout linear regulator designed for applications requiring stable voltage regulation with minimal power dissipation.  
- It features internal current limiting and thermal shutdown protection.  
- Suitable for battery-powered and automotive applications due to its wide input voltage range.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limit Protection:** Safeguards against overcurrent conditions.  
- **Reverse Battery Protection:** Withstands reverse polarity conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Wide Input Voltage Range:** Supports a broad range of power sources.  

This information is based on the manufacturer's datasheet for the LM2937IMPX-2.5.
