Description and Introduction

5A Ultra Low Dropout Voltage Regulator Fast Response, Adjustable & Fixed The SPX1581U5 is a low dropout (LDO) voltage regulator manufactured by SIPEX (now part of Exar Corporation). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.75V to 16V  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** 1.3V (typical at full load)  
- **Line Regulation:** 0.02% (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 SPX1581U5 is a high-performance LDO regulator designed for applications requiring stable and efficient power supply.  
- It provides a fixed 3.3V output with low noise and high ripple rejection.  
- The regulator includes thermal shutdown and current limit protection for enhanced reliability.  

### **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:** Protects against short circuits and overloads.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.
