Description and Introduction

5A Ultra Low Dropout Voltage Regulator Fast Response, Adjustable & Fixed The SPX1581T5 is a low dropout (LDO) voltage regulator manufactured by SIPEX (now part of Exar Corporation). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 1.5A  
- **Dropout Voltage:** 1.3V (typical at full load)  
- **Input Voltage Range:** 6.5V to 12V  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220-5 (through-hole)  

### **Descriptions:**  
- The SPX1581T5 is a high-performance LDO regulator designed for applications requiring stable 5V power.  
- It includes thermal shutdown and current limit protection for enhanced reliability.  
- Suitable for industrial, automotive, and consumer electronics applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal power loss.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive output current.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **High PSRR (Power Supply Rejection Ratio):** Reduces noise in sensitive circuits.  

For detailed datasheets, refer to Exar Corporation's documentation (SIPEX legacy products).
