Description and Introduction

Low Dropout Voltage Regulator The part **KA278R09** is a voltage regulator IC manufactured by **FAI**. Below are the factual specifications, descriptions, and features based on available information:  

### **Specifications:**  
- **Manufacturer:** FAI (Fairchild Semiconductor)  
- **Type:** Positive Voltage Regulator  
- **Output Voltage:** 9V  
- **Output Current:** Up to 1A (typical)  
- **Input Voltage Range:** Up to 35V (maximum)  
- **Dropout Voltage:** ~2V (typical)  
- **Package Type:** TO-220 (standard through-hole package)  
- **Operating Temperature Range:** Typically -40°C to +125°C  
- **Regulation Type:** Linear (fixed output)  

### **Descriptions:**  
The **KA278R09** is a fixed 9V linear voltage regulator designed to provide stable power supply output for electronic circuits. It is commonly used in applications requiring a regulated 9V DC supply from a higher input voltage.  

### **Features:**  
- **Fixed 9V Output:** Ensures a stable voltage supply.  
- **Overcurrent Protection:** Safeguards against excessive current draw.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Enhances reliability in fault conditions.  
- **Low Ripple & Noise:** Suitable for sensitive analog/digital circuits.  

This information is based on standard specifications for similar 78xx series regulators. For exact details, refer to the official FAI datasheet.
