- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA)  
- **Input Voltage Range:** 2.5V to 16V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 1.1mA (typical)  
- **Package:** 8-Pin SOIC (MSOP-8)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:**  
  - Thermal shutdown  
  - Current limit  
  - Reverse battery protection  

### **Descriptions:**  
The LP2987AIM-2.5 is a high-performance LDO regulator designed for applications requiring precise voltage regulation. It provides stable 2.5V output with low noise and high PSRR (Power Supply Rejection Ratio), making it suitable for sensitive analog and digital circuits.  

### **Features:**  
- Ultra-low dropout voltage (300mV at 500mA)  
- Low noise output  
- Fast transient response  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Reverse battery protection  
- Thermal shutdown and current limit protection  
- High PSRR (60dB at 1kHz)  

This regulator is commonly used in battery-powered devices, portable electronics, and precision analog circuits.
