- **Output Current:** Up to 1A  
- **Dropout Voltage:** 0.5V (typical at 1A)  
- **Input Voltage Range:** Up to 16V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220  

### **Descriptions:**  
- The SPX4041N is a low-dropout (LDO) linear voltage regulator designed for high-performance applications.  
- It provides stable output voltage with low noise and high efficiency.  
- Suitable for battery-powered devices, industrial systems, and consumer electronics.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Adjustable Output:** Allows flexibility in setting the desired voltage.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards the regulator during fault conditions.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.
