Description and Introduction

500 mA Low Dropout Regulator 3-DDPAK/TO-263 -40 to 125 The LM2937ESX-8.0/NOPB is a low-dropout voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 8.0V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 0.5V (typical at full load)  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223 (ESX)  

### **Descriptions:**  
The LM2937ESX-8.0/NOPB is a positive voltage regulator designed to maintain a stable 8.0V output with low dropout voltage, making it suitable for battery-powered applications. It includes features like reverse-battery protection, thermal shutdown, and current limiting.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- Reverse-battery protection  
- Internal thermal shutdown  
- Short-circuit and current-limit protection  
- Stable with low-ESR capacitors  
- Wide input voltage range (up to 26V)  

This regulator is commonly used in automotive, industrial, and consumer electronics applications.  

(Note: NS refers to National Semiconductor, which was acquired by Texas Instruments.)
