Description and Introduction

1.2V TO 37V ADJUSTABLE VOLTAGE REGULATOR The LM217K is a voltage regulator manufactured by NS (National Semiconductor). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage Range:** Adjustable from **1.2V to 37V**  
- **Output Current:** **1.5A** (maximum)  
- **Input-Output Voltage Differential:** **40V** (maximum)  
- **Line Regulation:** **0.01%/V** (typical)  
- **Load Regulation:** **0.1%** (typical)  
- **Operating Junction Temperature Range:** **-25°C to +150°C**  
- **Thermal Resistance (Junction-to-Case):** **5°C/W**  
- **Package Type:** **TO-3 (K)**  

### **Description:**  
The LM217K is an adjustable positive voltage regulator designed to supply **1.5A** of output current with a voltage range of **1.2V to 37V**. It requires only two external resistors to set the output voltage. The device includes internal current limiting, thermal shutdown, and safe operating area protection, making it robust against overloads.  

### **Features:**  
- **Adjustable Output Voltage** (1.2V to 37V)  
- **Guaranteed 1.5A Output Current**  
- **Internal Thermal Overload Protection**  
- **Short-Circuit Protection**  
- **Low Cost and Easy to Use**  
- **High Ripple Rejection** (80dB typical)  
- **Operates in High-Temperature Environments** (up to 150°C junction temperature)  

This information is strictly based on the manufacturer's datasheet for the LM217K by National Semiconductor (NS).
