Description and Introduction

1A Low Dropout Positive Voltage Regulator The LM1117-3.3 is a low dropout voltage regulator manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** 1.2V (typical) at full load  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** TO-220, TO-252 (DPAK), SOT-223  
- **Input Voltage Range:** Up to 15V  

### **Descriptions:**  
- The LM1117-3.3 is a positive voltage regulator designed to provide a fixed 3.3V output with high accuracy.  
- It is suitable for applications requiring stable voltage with low dropout, such as microcontrollers, FPGAs, and other digital circuits.  
- The device includes current limiting and thermal shutdown protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even when the input voltage is close to the output.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards the regulator and load.  
- **Available in Multiple Packages:** Offers flexibility for different PCB layouts.  

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