Description and Introduction

Low drop adjustable positive voltage regulator The LD1117AV is a low dropout voltage regulator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Voltage:** Adjustable (requires external resistors)  
- **Output Current:** Up to 800 mA  
- **Dropout Voltage:** Typically 1.2V at full load  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220  

### **Descriptions:**  
- The LD1117AV is a positive voltage regulator designed for low dropout applications.  
- It provides stable output voltage with minimal input-output differential.  
- Suitable for battery-powered devices and other applications requiring efficient voltage regulation.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Overcurrent Protection:** Safeguards against excessive current draw.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Adjustable Output:** Allows for flexibility in setting the desired output voltage.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to STMicroelectronics' official documentation.
