Description and Introduction

POSITIVE VOLTAGE REGULATORS The **L7808CV** is a **positive voltage regulator** manufactured by **STMicroelectronics (STM)**. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** +8V (fixed)  
- **Output Current:** Up to **1.5A**  
- **Input Voltage Range:** Up to **35V** (recommended input voltage ≥ 10.5V for stable regulation)  
- **Dropout Voltage:** **2V (typical)** at full load  
- **Line Regulation:** **0.03% (typical)**  
- **Load Regulation:** **0.1% (typical)**  
- **Operating Temperature Range:** **0°C to +125°C**  
- **Package:** **TO-220 (3 pins)**  

### **Descriptions:**
- The **L7808CV** is a **linear voltage regulator** that provides a stable **+8V DC output** from an unregulated DC input.  
- It includes **internal thermal overload protection, short-circuit protection, and output transistor safe operating area protection**.  
- Designed for **fixed-voltage applications**, it does not require external components for basic operation (though capacitors may be needed for stability).  

### **Features:**
- **Thermal Overload Protection** – Shuts down if temperature exceeds safe limits.  
- **Short-Circuit Protection** – Safeguards against excessive current.  
- **No External Components Required** (except for input/output capacitors in some cases).  
- **Low Cost and Reliable** – Suitable for industrial, consumer, and automotive applications.  

This regulator is commonly used in power supplies, battery chargers, and other circuits requiring a stable **+8V** output.
