Description and Introduction

0.8A Fixed LDO Linear Regulator in a SOIC 8-Lead package The IRU1117-3.3CS is a low dropout (LDO) voltage regulator manufactured by IR (International Rectifier). Below are its key specifications, descriptions, and features:

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

### **Descriptions:**
- The IRU1117-3.3CS is a positive voltage regulator designed to provide a stable 3.3V output.  
- It is suitable for applications requiring low dropout voltage and high current capability.  
- Includes built-in thermal shutdown and current limiting for protection.  

### **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 Protection:** Prevents damage from overheating.  
- **Current Limiting:** Protects against short circuits and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum capacitors.  

This regulator is commonly used in power supplies for microcontrollers, FPGAs, and other low-voltage digital circuits.
