Description and Introduction

800mA Low-Dropout Linear Regulator The LM1117SX-3.3 is a low dropout voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** 1.2V (typical) at full load  
- **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  

### **Descriptions:**  
- The LM1117SX-3.3 is a positive voltage regulator designed to provide a stable 3.3V output.  
- It is suitable for applications requiring low dropout voltage and high efficiency.  
- The device includes current limiting and thermal shutdown protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even when the input voltage is close to the output.  
- **Fixed Output Voltage:** Eliminates the need for external resistors.  
- **Current Limiting & Thermal Protection:** Safeguards the regulator from damage due to excessive current or temperature.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **Compact SOT-223 Package:** Ideal for space-constrained applications.  

This information is based on the manufacturer's datasheet. For detailed performance curves and application notes, refer to the official documentation.
