Description and Introduction

1A Low Dropout Regulator The LM2940LD-15 is a low-dropout voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage:** 15V  
- **Output Current:** 1A  
- **Dropout Voltage:** Typically 0.5V 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-252 (DPAK)  

### **Descriptions & Features:**  
- **Low Dropout:** Ensures stable regulation even when input voltage is close to output.  
- **Internal Current Limiting & Thermal Shutdown:** Protects against overloads and overheating.  
- **Reverse Battery Protection:** Withstands reverse polarity conditions.  
- **Low Quiescent Current:** Improves efficiency in battery-operated applications.  
- **Stable with Low-ESR Capacitors:** Works reliably with inexpensive capacitors.  

The LM2940LD-15 is commonly used in automotive, industrial, and consumer electronics applications requiring stable 15V power.
