- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Input Voltage Range:** 2.5V to 16V  
- **Low Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5 (Miniature 5-Pin Package)  
- **Accuracy:** ±1.5% (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 performance improves efficiency in low-voltage systems.  
- Stable with low-ESR ceramic capacitors (≥1µF).  
- Low noise and fast transient response.  
- Suitable for portable devices, wireless applications, and power-sensitive circuits.  
- Pin-compatible with other SOT-23-5 LDO regulators.  

This regulator is optimized for space-constrained designs due to its small SOT-23-5 package.
