Description and Introduction

THREE TERMINAL POSITIVE FIXED VOLTAGE REGULATORS The LM340T15 is a fixed voltage regulator manufactured by National Semiconductor (NS). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 15V  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** 17.5V to 35V  
- **Line Regulation:** 0.015% (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Dropout Voltage:** 2V (Typical)  
- **Operating Junction Temperature Range:** 0°C to +125°C  
- **Package Type:** TO-220  

### **Descriptions:**  
The LM340T15 is a three-terminal positive voltage regulator designed to provide a fixed 15V output with a maximum current of 1.5A. It includes internal current limiting, thermal shutdown, and safe operating area protection, making it robust against overload conditions.  

### **Features:**  
- Fixed 15V output  
- Internal thermal overload protection  
- Short-circuit current limiting  
- No external components required for operation  
- Available in a TO-220 package for easy mounting  

This information is based on the manufacturer's datasheet.
