- **Input Voltage Range:** 4.3V to 30V  
- **Line Regulation:** 0.3% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-92, SOT-223  

### **Descriptions:**  
- The LP2951ACS-5.0 is a precision voltage regulator designed for low-power applications.  
- It features low dropout voltage, making it suitable for battery-powered systems.  
- Includes built-in protection against reverse battery, overcurrent, and overtemperature conditions.  
- Stable with low-ESR capacitors (≥1µF).  

### **Features:**  
- Low quiescent current for improved efficiency.  
- Adjustable output version available (LP2951ACZ).  
- Error flag output for low-voltage detection.  
- Thermal shutdown protection.  
- Short-circuit and reverse polarity protection.
