Description and Introduction

3-Terminal Adjustable Regulator The LM317AMDT is a linear voltage regulator manufactured by National Semiconductor (国半). Below are the specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Output Voltage Range:** Adjustable from **1.2V to 37V**  
- **Output Current:** Up to **1.5A**  
- **Input-Output Voltage Differential (Dropout Voltage):** **3V (max)**  
- **Line Regulation:** **0.01%/V (typ)**  
- **Load Regulation:** **0.1% (typ)**  
- **Operating Junction Temperature:** **-40°C to +125°C**  
- **Package:** **TO-252 (DPAK)**  

### **Descriptions:**  
- The LM317AMDT is a **positive adjustable voltage regulator** designed to supply more than **1.5A** of load current with an adjustable output voltage.  
- It includes **internal current limiting, thermal shutdown, and safe operating area protection**, making it robust against overload conditions.  
- The regulator is **stable with only an output capacitor** but improves transient response with an input bypass capacitor.  

### **Features:**  
- **Adjustable Output Voltage** (set via external resistors)  
- **Overcurrent and Overtemperature Protection**  
- **Low Thermal Resistance (TO-252 Package)**  
- **Wide Input Voltage Range** (up to 40V)  
- **Improved Line and Load Regulation** compared to fixed regulators  

This information is strictly based on the manufacturer's datasheet and specifications.
