### **Descriptions:**  
The LT3021 is a low dropout (LDO) linear regulator designed for low voltage applications. It features very low dropout voltage and ultra-low quiescent current, making it suitable for battery-powered systems.  

### **Features:**  
- Low dropout voltage (300mV typical at 500mA)  
- Ultra-low quiescent current (30µA typical)  
- Adjustable output voltage (0.4V to 9.5V)  
- Stable with low ESR ceramic capacitors (≥10µF)  
- Current limit and thermal shutdown protection  
- Low noise operation  
- Reverse-battery protection  
- Available in small SOT-23 and MSOP packages  

This information is based on the official datasheet from Linear Technology (Analog Devices).
