### **Descriptions:**  
The LD1117S18TR is a low-dropout (LDO) linear voltage regulator from STMicroelectronics, designed to provide a stable 1.8V output. It is suitable for applications requiring precise voltage regulation with low power dissipation.  

### **Features:**  
- Fixed 1.8V output voltage  
- Low dropout voltage (1.1V typical at full load)  
- Overcurrent and thermal protection  
- High accuracy (±1% output voltage tolerance)  
- Low quiescent current  
- Stable with low-ESR ceramic capacitors (≥10µF recommended)  
- RoHS compliant  

This regulator is commonly used in power supply circuits for microcontrollers, FPGAs, and other low-voltage digital systems.
