Description and Introduction

800mA LOW DROPOUT POSITIVE FIXED 3.3V REGULATOR The IRU1117-3.3 is a low dropout (LDO) linear voltage regulator manufactured by IR (International Rectifier). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 15V  
- **Dropout Voltage:** Typically 1.1V at 800mA load  
- **Output Current:** Up to 1A (with proper heat sinking)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-252 (DPAK), TO-263 (D2PAK), and SOT-223  

### **Descriptions:**  
- The IRU1117-3.3 is a fixed-output LDO regulator designed for applications requiring stable 3.3V power.  
- It includes overcurrent and thermal protection for enhanced reliability.  
- Suitable for industrial, automotive, and consumer electronics applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Thermal & Overcurrent Protection:** Safeguards against overheating and excessive current.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum capacitors for output stability.  
- **Pb-Free & RoHS Compliant:** Meets environmental standards.  

This information is based solely on IR's documented specifications for the IRU1117-3.3 regulator.
