Description and Introduction

Adjustable and fixed low drop positive voltage regulator The LD1117S18CTR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics (ST). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** 1.1V (typical at 800mA)  
- **Input Voltage Range:** Up to 15V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223 (surface-mount)  
- **Thermal Resistance (Junction-to-Ambient):** 62°C/W  

### **Descriptions:**  
- The LD1117S18CTR is a fixed-output LDO regulator designed for applications requiring stable and efficient voltage regulation.  
- It includes features like current limiting and thermal shutdown for protection.  
- Suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Overcurrent & Thermal Protection:** Safeguards the device under fault conditions.  
- **Low Quiescent Current:** Improves efficiency in standby mode.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
