- **Output Current:** 800mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 2.5V to 7V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.04% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Pin SOT-223  

### **Descriptions:**
- The LP3966ES-1.8 is a high-performance LDO regulator designed for low-power applications.  
- It provides stable and precise voltage regulation with low dropout and low quiescent current.  
- Suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal input-output differential.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards against overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors for space-saving designs.  
- **Fast Transient Response:** Maintains stable output under dynamic load conditions.  

This information is based on the manufacturer's datasheet. For detailed performance curves and application notes, refer to the official NSC documentation.
