Description and Introduction

1A Low Dropout Regulator 4-SOT-223 -40 to 85 The LM2940IMP-5.0NOPB is a low-dropout voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage:** 5.0V  
- **Output Current:** 1A  
- **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:** TO-263-5 (D2PAK)  

### **Descriptions:**  
- The LM2940 is a fixed-output, low-dropout regulator designed to provide up to 1A of output current.  
- It includes features such as reverse battery protection, thermal shutdown, and current limiting for enhanced reliability.  
- Suitable for battery-powered applications due to its low quiescent current and dropout voltage.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- Reverse battery protection  
- Internal short-circuit current limit  
- Thermal shutdown protection  
- High ripple rejection (75dB typical)  
- Stable with low-ESR capacitors  

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