Description and Introduction

3-Terminal 1A Negative Voltage Regulator The part **KA7918TU** is a negative voltage regulator manufactured by **SEC (Samsung Electronics)**.  

### **Specifications:**  
- **Output Voltage:** -18V  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** Up to -35V (recommended to stay within operational limits)  
- **Dropout Voltage:** Typically 2V (input must be at least 2V more negative than the output)  
- **Package:** TO-220 (through-hole mounting)  
- **Operating Temperature Range:** Typically -25°C to +125°C  

### **Descriptions & Features:**  
- Fixed **-18V** output voltage  
- **Overcurrent protection** to prevent damage from excessive load  
- **Thermal shutdown** for protection against overheating  
- **Internal short-circuit current limiting**  
- **High ripple rejection ratio** for stable output  
- Suitable for power supply applications requiring a regulated negative voltage  

This regulator is commonly used in analog circuits, audio amplifiers, and other electronic systems requiring a stable negative voltage supply.  

(Note: Always refer to the official datasheet for precise specifications and application details.)
