- **Dropout Voltage:** 300mV (typical at 100mA load)  
- **Input Voltage Range:** Up to 16V  
- **Quiescent Current:** 75µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP2981AIM5-5.0 is a precision LDO regulator designed for low-power applications.  
- It provides stable 5.0V output with low noise and high accuracy.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.  

This information is based on the manufacturer's datasheet for the LP2981AIM5-5.0.
