Description and Introduction

0.3A Fixed LDO Linear Regulator in a SOT-23 5-Leads package The IRU1205-28CLTR is a step-down DC-DC converter module manufactured by Infineon Technologies. Below are the key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage:** 0.8V to 5.5V (adjustable)  
- **Output Current:** Up to 5A  
- **Efficiency:** Up to 96%  
- **Switching Frequency:** 600 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 28-pin CLCC (Ceramic Leadless Chip Carrier)  

### **Descriptions:**  
- A non-isolated, synchronous buck converter module.  
- Designed for high-efficiency power conversion in industrial, automotive, and telecom applications.  
- Integrates power MOSFETs, PWM controller, and passive components in a compact package.  

### **Features:**  
- **Integrated Power Stage:** Includes high-side and low-side MOSFETs.  
- **Adjustable Output:** Set via external resistors.  
- **Protection Features:** Overcurrent, overtemperature, and undervoltage lockout (UVLO).  
- **Soft-Start:** Reduces inrush current during startup.  
- **Synchronous Rectification:** Improves efficiency and reduces heat dissipation.  
- **Compact Design:** Suitable for space-constrained applications.  

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

Application Scenarios & Design Considerations

0.3A Fixed LDO Linear Regulator in a SOT-23 5-Leads package

Alternative Part Number

  • LP2985AIM5-2.8 --: Low-dropout linear regulator with 2.8V fixed output in SOT-23-5, functionally equivalent to the IRU1205-28 in similar low-current applications.
  • MIC5205-2.8YM5 --: 2.8V fixed LDO regulator in SOT-23-5 with comparable dropout and current capability, a common drop-in style replacement.
  • AP2112K-2.8TRG1 --: 2.8V fixed LDO in SOT-23-5 with low dropout and good availability, suitable as an alternative regulator for the same rail.
