### **Specifications:**  
- **Output Voltage:** -12V  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** -14.5V to -35V (for -12V output)  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 0.1% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Thermal Resistance (Junction-to-Case):** 3°C/W  
- **Package:** TO-220  

### **Descriptions:**  
- The L7912CV is a fixed negative voltage regulator designed to provide a stable -12V output.  
- It includes internal current limiting, thermal shutdown, and safe operating area protection.  
- Suitable for applications requiring regulated negative voltage supplies.  

### **Features:**  
- **Fixed Output Voltage:** -12V ±4%  
- **High Ripple Rejection Ratio:** 55dB (typical)  
- **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.  

This information is based on the manufacturer's datasheet and technical documentation.
