### **Specifications:**  
- **Output Voltage:** +12V  
- **Output Current:** 500mA  
- **Input Voltage Range:** Up to 35V  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 0.03%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package Types:** TO-220, TO-252 (DPAK), TO-263 (D2PAK)  

### **Descriptions:**  
- The LM78M12 is a fixed positive voltage regulator designed to provide a stable +12V output.  
- It includes internal current limiting, thermal shutdown, and safe-operating-area protection.  
- Suitable for a wide range of applications, including power supplies, industrial controls, and consumer electronics.  

### **Features:**  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards against output short circuits.  
- **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.
