- **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-5.0 is a high-performance LDO regulator designed for applications requiring stable and precise voltage regulation.  
- It features low dropout voltage, making it suitable for battery-powered devices.  
- The regulator includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limit Protection:** Safeguards against output short circuits.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.  

The LP3966ES-5.0 is commonly used in portable electronics, embedded systems, and power-sensitive applications.
