Description and Introduction

THREE-TERMINAL MEDIUM CURRENT POSITIVE FIXED VOLTAGE REGULATORS # **MC78M20CT: A Reliable 20V Voltage Regulator for Your Electronic Designs**  

When designing electronic circuits, stability and reliability are paramount. The MC78M20CT is a fixed-output voltage regulator that delivers a consistent 20V DC output, making it an ideal choice for applications requiring dependable power management.  

## **Key Features**  

- **Fixed 20V Output:** Ensures a stable voltage supply, reducing the risk of fluctuations that could damage sensitive components.  
- **High Current Capacity:** Capable of delivering up to 500mA, suitable for a variety of low to moderate power applications.  
- **Thermal Overload Protection:** Built-in safeguards prevent overheating, enhancing device longevity.  
- **Short-Circuit Protection:** Automatically limits current in case of a fault, protecting both the regulator and connected circuitry.  
- **Wide Operating Temperature Range:** Performs reliably in varying environmental conditions, from industrial to consumer applications.  

## **Applications**  

The MC78M20CT is versatile, fitting seamlessly into numerous electronic systems, including:  
- Power supplies for embedded systems  
- Industrial control circuits  
- Automotive electronics  
- Consumer electronics requiring stable voltage regulation  

## **Why Choose the MC78M20CT?**  

Engineers and designers favor the MC78M20CT for its robustness and ease of integration. Its TO-220 package allows for efficient heat dissipation, while its straightforward design minimizes the need for additional external components. Whether used in prototyping or mass production, this regulator ensures consistent performance, making it a trusted component in power management solutions.  

For projects demanding a dependable 20V power source, the MC78M20CT stands out as a cost-effective and efficient solution.

Application Scenarios & Design Considerations

THREE-TERMINAL MEDIUM CURRENT POSITIVE FIXED VOLTAGE REGULATORS

Alternative Part Number

  • L7820CV --: Fixed 20V positive linear regulator in TO-220, same 0.5A class and pinout as the MC78M20CT, widely available and a direct functional drop-in.
  • UA7820CKCS --: 20V fixed positive voltage regulator in TO-220 with 0.5A output, equivalent 78M20-class performance and pin-compatible replacement.
  • LM7820CT --: Standard 20V fixed linear regulator in TO-220, same voltage and current rating, suitable as a cross-manufacturer substitute for the Motorola part.
