- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Low Shutdown Current:** 0.01µA (typical)  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit  

### **Descriptions and Features:**  
- **Ultra-Low Dropout:** Ensures stable operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum capacitors (≥1µF).  
- **Enable Pin:** Allows for power-saving shutdown mode.  
- **Applications:** Battery-powered devices, portable electronics, and precision voltage regulation.  

This regulator is designed for high-performance, space-constrained applications requiring stable and efficient power management.
