Description and Introduction

5A Low Dropout Positive Regulators The LM1084IT-3.3 is a low dropout voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (Fixed)  
- **Output Current:** Up to 5A  
- **Dropout Voltage:** 1.3V (Typical at 5A)  
- **Line Regulation:** 0.015% (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (3-Lead)  
- **Input Voltage Range:** Up to 30V  
- **Quiescent Current:** 10mA (Typical)  
- **Protection Features:** Thermal Shutdown, Current Limit  

### **Descriptions:**
The LM1084IT-3.3 is a high-current, low-dropout (LDO) voltage regulator designed to provide a stable 3.3V output with up to 5A of load current. It is suitable for applications requiring high efficiency and low power dissipation. The device includes thermal shutdown and current limit protection for enhanced reliability.

### **Features:**
- **High Current Capability:** Supports up to 5A output current.  
- **Low Dropout Voltage:** 1.3V typical at full load.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Thermal Protection:** Built-in thermal shutdown prevents overheating.  
- **Current Limiting:** Protects against short circuits and overloads.  
- **Wide Input Voltage Range:** Up to 30V input.  
- **Stable with Low-ESR Capacitors:** Works effectively with ceramic or tantalum capacitors.  

This regulator is commonly used in power supply designs for industrial, automotive, and computing applications.
