Description and Introduction

7A Ultra Low Dropout Voltage Regulator Fast Response, Adjustable & Fixed The SPX1580T5 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:** Fixed 5V  
- **Output Current:** Up to 3A  
- **Dropout Voltage:** Typically 1.3V at full load (3A)  
- **Input Voltage Range:** 6.5V to 16V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-263-5 (D2PAK)  

### **Descriptions:**  
- The SPX1580T5 is a high-current, low-dropout linear regulator designed for applications requiring stable 5V power.  
- It includes thermal shutdown, current limit, and reverse-battery protection for reliability.  
- Suitable for industrial, automotive, and consumer electronics applications.  

### **Features:**  
- **High Output Current:** Supports up to 3A continuous load.  
- **Low Dropout Voltage:** Ensures efficient operation with minimal input-output differential.  
- **Thermal Protection:** Prevents overheating damage.  
- **Current Limiting:** Protects against short circuits.  
- **Reverse-Battery Protection:** Guards against incorrect power supply connections.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  

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