Description and Introduction

3-Terminal Adjustable Regulator The LM317S is a three-terminal adjustable positive voltage regulator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Voltage Range:** 1.2V to 37V  
- **Output Current:** Up to 1.5A  
- **Input-Output Voltage Differential (Dropout Voltage):** 3V (typical)  
- **Line Regulation:** 0.01%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Operating Junction Temperature Range:** 0°C to +125°C  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
The LM317S is designed to provide a stable, adjustable output voltage with only two external resistors. It includes internal current limiting, thermal shutdown, and safe operating area protection, making it robust against overloads.  

### **Features:**  
- Adjustable output voltage  
- 1.5A output current capability  
- Internal thermal overload protection  
- Short-circuit protection  
- P+ product enhancement tested  

This regulator is commonly used in power supply circuits requiring precise voltage control.
