Description and Introduction

3A Fixed LDO Linear Regulator in a TO-263 3-Leads package The IRU1030-33CMTR is a voltage regulator module manufactured by International Rectifier (IR). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** International Rectifier (IR)  
- **Part Number:** IRU1030-33CMTR  
- **Output Voltage:** 3.3V  
- **Input Voltage Range:** 4.5V to 13.2V  
- **Output Current:** Up to 30A  
- **Efficiency:** High efficiency (typically >90%)  
- **Package Type:** Surface Mount (SMD)  
- **Switching Frequency:** Adjustable (typically 300kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Overcurrent, Overtemperature, Undervoltage Lockout (UVLO)  

### **Descriptions:**  
- The IRU1030-33CMTR is a high-performance, non-isolated DC-DC converter designed for point-of-load (POL) applications.  
- It provides a regulated 3.3V output from a wide input voltage range, making it suitable for various power supply designs.  
- The module integrates power MOSFETs, PWM controller, and passive components for a compact solution.  

### **Features:**  
- **High Efficiency:** Optimized for low power loss.  
- **Adjustable Switching Frequency:** Allows optimization for noise and efficiency.  
- **Integrated Power Components:** Simplifies design and reduces external component count.  
- **Protection Mechanisms:** Includes overcurrent, overtemperature, and undervoltage lockout for reliability.  
- **Surface-Mount Package:** Suitable for automated PCB assembly.  

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

Application Scenarios & Design Considerations

3A Fixed LDO Linear Regulator in a TO-263 3-Leads package

Alternative Part Number

  • LM3940IS-3.3 --: Low-dropout 3.3V linear regulator in a similar TO-263 style package with comparable current capability, widely available and pin-compatible in most designs.
  • MIC29302WU --: Adjustable low-dropout regulator that can be set to 3.3V, offers similar or higher current rating and thermal performance in a TO-263 package.
  • AMS1117-3.3 --: Common 3.3V LDO regulator with similar function and package options; lower cost alternative though with somewhat lower current margin, suitable for less demanding loads.
