- **Type:** Voltage Regulator IC  
- **Output Voltage:** 5V  
- **Output Current:** 500mA (0.5A)  
- **Input Voltage Range:** 7V to 20V  
- **Dropout Voltage:** 2V (typical)  
- **Package Type:** TO-220 (5-pin)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent protection, thermal shutdown  

### **Descriptions:**  
- The **M5278L05M** is a linear voltage regulator IC designed to provide a stable **5V output** from a higher input voltage.  
- It is commonly used in power supply circuits for electronic devices requiring a regulated 5V supply.  
- The **TO-220 package** allows for efficient heat dissipation, making it suitable for medium-power applications.  

### **Features:**  
- **Fixed 5V Output** – Ensures stable voltage regulation.  
- **High Ripple Rejection** – Reduces noise in the output voltage.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Overcurrent Protection** – Safeguards the IC and connected components.  
- **Wide Input Voltage Range (7V–20V)** – Supports various power sources.  

This information is strictly based on manufacturer specifications and technical documentation.
