- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV typical at full load (150mA)  
- **Input Voltage Range:** 2.5V to 16V  
- **Line Regulation:** 0.02% typical  
- **Load Regulation:** 0.04% typical  
- **Quiescent Current:** 75µA typical  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LP2985ITPX-3.3 is a high-accuracy, low-noise LDO regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low dropout, making it suitable for portable and noise-sensitive systems.  
- Includes built-in protection features such as thermal shutdown and current limit.  

### **Features:**
- **Ultra-Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications like RF and analog circuits.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

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