- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 0.5V (typical at full load)  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Descriptions:**  
The LM2937IMPX-12 is a fixed-output, low-dropout regulator designed for applications requiring stable voltage regulation with minimal input-output differential. It features reverse-battery protection, thermal shutdown, and current limiting for enhanced reliability.  

### **Features:**  
- Low dropout voltage (0.5V typical at full load)  
- Reverse-battery protection  
- Internal thermal shutdown  
- Short-circuit current limiting  
- Stable with low-ESR capacitors  
- Wide input voltage range (up to 26V)  
- Available in a surface-mount DPAK package  

This regulator is commonly used in automotive, industrial, and battery-powered applications.
