Description and Introduction

3A Low Dropout Voltage Regulator Adjustable & Fixed Output, Fast Response The SPX1587AU-3.3 is a low-dropout (LDO) voltage regulator manufactured by SIPEX (now part of Exar Corporation). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 3A  
- **Dropout Voltage:** 1.3V (typical at full load)  
- **Input Voltage Range:** 4.75V to 16V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263-5 (D2PAK)  

### **Descriptions:**  
- The SPX1587AU-3.3 is a high-current, low-dropout linear regulator designed for applications requiring stable power with minimal voltage fluctuations.  
- It includes thermal shutdown and current limit protection for enhanced reliability.  
- Suitable for industrial, automotive, and consumer electronics applications.  

### **Features:**  
- **High Output Current:** Supports up to 3A.  
- **Low Dropout Voltage:** Ensures efficient operation even when input voltage is close to the output.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Current Limiting:** Protects against short circuits and overloads.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Fast Transient Response:** Maintains stable output under load variations.  

This information is strictly based on the manufacturer's datasheet and does not include any additional recommendations or guidance.
