Description and Introduction

1A Fixed LDO Linear Regulator in a SOT-223 3-Leads package The IRU1010-33CY is a low dropout (LDO) voltage regulator manufactured by IR (International Rectifier). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 10V  
- **Dropout Voltage:** 1.1V (typical at 1A load)  
- **Output Current:** 1A (maximum)  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Descriptions:**  
- The IRU1010-33CY is a fixed-output LDO regulator designed for applications requiring stable voltage with low dropout.  
- It provides overcurrent and thermal protection for enhanced reliability.  
- Suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal input-output differential.  
- **Thermal & Overcurrent Protection:** Safeguards against overheating and excessive current.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.  
- **Fixed Output Voltage:** Eliminates the need for external resistors.  

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