Description and Introduction

1A VERY LOW DROPOUT POSITIVE FIXED AND ADJUSTABLE REGULATORS The IRU1209 is a high-speed, low-power infrared receiver module designed for remote control applications.  

### **Manufacturer Specifications:**  
- **Operating Voltage:** 2.7V to 5.5V  
- **Carrier Frequency:** 38kHz (typical)  
- **Supply Current:** 0.35mA (typical)  
- **Output Signal:** Active Low  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package Type:** 3-pin epoxy package  

### **Descriptions and Features:**  
- **High Sensitivity:** Capable of receiving weak infrared signals.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Built-in AGC (Automatic Gain Control):** Ensures stable performance under varying signal conditions.  
- **Wide Operating Voltage Range:** Compatible with 3V and 5V systems.  
- **Compact Design:** Small form factor for space-constrained applications.  
- **Immunity to Ambient Light:** Minimizes interference from external light sources.  

This module is commonly used in TVs, air conditioners, and other consumer electronics requiring infrared remote control functionality.

Description and Introduction

1A VERY LOW DROPOUT POSITIVE FIXED AND ADJUSTABLE REGULATORS The IRU1209 is a step-down DC-DC converter manufactured by IOR (Integrated Operational Resources). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 13.2V  
- **Output Voltage:** Adjustable from 1.23V to 10V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TO-263 (D2PAK)  

### **Descriptions:**  
The IRU1209 is a synchronous buck regulator designed for high-efficiency power conversion. It integrates both high-side and low-side MOSFETs, reducing external component count. The device is suitable for applications requiring compact power solutions with high efficiency and low heat dissipation.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Integrated MOSFETs:** Simplifies PCB design.  
- **Overcurrent Protection:** Prevents damage during load faults.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Soft-Start Function:** Reduces inrush current during startup.  

For detailed application notes and schematics, refer to the official IOR datasheet.
