- **Input Voltage Range:** Up to 16V  
- **Dropout Voltage:** 300mV (typical) at 150mA load  
- **Output Current:** 150mA (maximum)  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23 (5-pin)  

### **Descriptions:**
- The LP2980AIBP-3.3 is a precision LDO regulator designed for battery-powered applications.  
- It provides stable 3.3V output with low dropout voltage, making it suitable for low-power systems.  
- Features low quiescent current and thermal shutdown protection.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Noise Output:** Ideal for noise-sensitive applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the regulator during faults.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Low Ground Pin Current:** Enhances efficiency in battery-operated devices.  

This regulator is commonly used in portable electronics, embedded systems, and power-sensitive applications.
