- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions:**  
- The LP2985IM5X-2.8 is a high-performance LDO regulator designed for battery-powered applications.  
- It provides a stable 2.8V output with very low dropout voltage, making it suitable for low-input voltage conditions.  
- The device includes thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**  
- Ultra-low dropout voltage (300mV typical at 150mA)  
- Low noise output  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Fast transient response  
- Low quiescent current in operation and shutdown modes  
- Thermal shutdown and current limit protection  

This regulator is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications.
