- **Package:** TO-220-5 (through-hole)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
The LM2937ET-5.0/NOPB is a positive voltage regulator designed to provide a stable 5.0V output with low dropout voltage. It is suitable for battery-powered applications and automotive systems due to its wide input range and robust protection features.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- High accuracy (±2% output voltage tolerance)  
- Reverse battery protection  
- Internal thermal shutdown and current limiting  
- Stable with low-ESR capacitors  
- Suitable for harsh environments  

This regulator is commonly used in automotive electronics, industrial controls, and portable devices.
