Description and Introduction

1A Low Dropout Regulator 4-SOT-223 -40 to 85 The LM2940IMP-10/NOPB is a low-dropout voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage:** 10V  
- **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 (D2PAK)  

### **Descriptions:**  
The LM2940IMP-10/NOPB is a fixed-output, low-dropout regulator designed to provide a stable 10V output with up to 1A of current. It features internal current limiting, thermal shutdown, and reverse battery protection.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- Internal short-circuit current limiting  
- Thermal shutdown protection  
- Reverse battery protection  
- Low quiescent current  
- Output voltage tolerance of ±5%  

This regulator is suitable for applications requiring stable power supply with minimal dropout, such as automotive and industrial systems.
