Description and Introduction

400mA and 500mA Voltage Regulator The LM2937ET-2.5 is a low-dropout voltage regulator manufactured by National Semiconductor (NS).  

### **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 Type:** TO-220 (5-pin)  

### **Descriptions:**  
The LM2937ET-2.5 is a positive voltage regulator designed to provide a stable 2.5V output with low dropout voltage. It is suitable for battery-powered applications and features reverse-battery protection, thermal shutdown, and current limiting for enhanced reliability.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- Reverse-battery protection  
- Internal thermal shutdown  
- Short-circuit protection  
- Stable with low-ESR capacitors  
- High ripple rejection  

This regulator is commonly used in automotive, industrial, and consumer electronics applications where stable voltage regulation is required.
