- **Output Current:** Up to 1A  
- **Dropout Voltage:** Typically 0.5V 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-263 (D2PAK)  

### **Descriptions & Features:**  
- Designed for low-voltage, high-current applications  
- Includes built-in thermal shutdown and current limit protection  
- Low dropout voltage ensures efficient regulation even with small input-output differentials  
- Stable with low-ESR output capacitors  
- Suitable for battery-powered and automotive applications  

This regulator is commonly used in power supply circuits requiring stable 8V output with minimal voltage drop.
