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 Options:** Fixed (1.8V, 2.5V, 3.3V, 5.0V) or adjustable (1.25V to 5.5V).  
- **Output Current:** Up to 1A.  
- **Dropout Voltage:** 1.3V (typical) at full load.  
- **Input Voltage Range:** Up 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 Type:** TO-263-5 (D²PAK).  

### **Descriptions:**  
- The SPX1581T5 is a high-performance LDO regulator designed for applications requiring stable voltage with low noise.  
- It features thermal shutdown and current limit protection.  
- Suitable for industrial, automotive, and consumer electronics.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Thermal Protection:** Prevents damage from overheating.  
- **Current Limiting:** Safeguards against excessive load currents.  
- **Wide Input Voltage Range:** Supports various power sources.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is based on the SIPEX datasheet for the SPX1581T5.
