- **Output Current:** 100mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 16V  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** <1µA  
- **Accuracy:** ±2% over line, load, and temperature  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Ultra-low dropout voltage ensures efficient operation with minimal power loss.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and high PSRR (Power Supply Rejection Ratio) for sensitive analog circuits.  
- Thermal shutdown and current limit protection enhance reliability.  
- Suitable for portable electronics, instrumentation, and power-sensitive applications.  

This information is based on the manufacturer's datasheet and technical documentation.
