Description and Introduction

POSITIVE VOLTAGE REGULATORS The L7820 is a fixed voltage regulator manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 20V  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** Up to 35V (recommended max 28V for reliable operation)  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 60mV (typical)  
- **Load Regulation:** 60mV (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package Options:** TO-220, TO-220FP, D²PAK  

### **Descriptions:**
- The L7820 is a positive voltage regulator in the 78xx series.  
- It provides a stable 20V output with built-in thermal overload protection and short-circuit protection.  
- Designed for use in various power supply applications requiring a fixed 20V output.  

### **Features:**
- **Thermal Overload Protection** – Shuts down the regulator if excessive temperature is detected.  
- **Short-Circuit Protection** – Safeguards against output short circuits.  
- **Internal Current Limiting** – Prevents damage due to excessive current draw.  
- **No External Components Required** – Only input and output capacitors are needed for stability.  
- **High Ripple Rejection** – Reduces noise in the output voltage.  

This information is based on the manufacturer's datasheet for the L7820 voltage regulator by STMicroelectronics.
