Description and Introduction

3-Terminal Positive Adjustable Regulator The LM317AHV by Fairchild Semiconductor is a high-voltage adjustable voltage regulator. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** Up to **60V**  
- **Output Voltage Range:** **1.2V to 57V**  
- **Output Current:** **1.5A** (continuous)  
- **Line Regulation:** **0.01%/V** (typical)  
- **Load Regulation:** **0.1%** (typical)  
- **Operating Temperature Range:** **-40°C to +125°C**  
- **Package Type:** **TO-39 (Metal Can)**  
- **Adjustment Pin Current:** **50µA** (typical)  
- **Thermal Resistance (Junction-to-Case):** **17°C/W**  

### **Descriptions:**  
- The LM317AHV is a high-voltage variant of the standard LM317 regulator, capable of handling input voltages up to 60V.  
- It provides a stable, adjustable output voltage with only two external resistors.  
- Designed for applications requiring higher input voltages than standard regulators.  

### **Features:**  
- **Adjustable Output Voltage** (1.2V to 57V)  
- **High Input Voltage Capability** (up to 60V)  
- **Overcurrent and Thermal Protection**  
- **Low Quiescent Current**  
- **Improved Line and Load Regulation**  
- **TO-39 Package for Robust Thermal Performance**  

This information is based on Fairchild Semiconductor's datasheet for the LM317AHV.
