Description and Introduction

1A Low Dropout Regulator 3-DDPAK/TO-263 0 to 125 The LM2940CS-15/NOPB is a low-dropout voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 15V (fixed)  
- **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-263 (D2PAK), 5-pin  

### **Descriptions:**  
The LM2940CS-15/NOPB is a positive voltage regulator designed to provide a stable 15V output with low dropout voltage. It is suitable for battery-powered applications and features built-in protection against reverse battery, short circuits, and thermal overload.  

### **Features:**  
- Low dropout voltage (0.5V typical at 1A)  
- Reverse battery protection  
- Internal short-circuit current limiting  
- Thermal shutdown protection  
- High ripple rejection (75dB typical)  
- Low quiescent current  
- Stable with low-ESR capacitors  

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