### **Descriptions:**  
The LTC3405AES6-1.8#PBF is a compact, high-performance step-down regulator designed for portable and battery-powered applications. It features a fixed 1.8V output and operates from a 2.5V to 5.5V input range, making it suitable for single-cell Li-ion or multi-cell alkaline/NiMH applications.  

### **Features:**  
- High efficiency synchronous operation  
- Low quiescent current in Burst Mode  
- No external Schottky diode required  
- Short-circuit and thermal protection  
- Small SOT-23-6 package  
- Fast transient response  
- Stable with ceramic capacitors  

This regulator is ideal for applications such as portable devices, wireless sensors, and handheld instruments where space and efficiency are critical.
