- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 175mV (typical) at 500mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 17µA (typical)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Package:** SOT-223-6 (DCQ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit, reverse current protection  

### **Descriptions:**  
The TPS72518DCQR is a low-power LDO regulator designed for applications requiring high efficiency and low noise. It provides a stable 1.8V output with excellent line and load regulation.  

### **Features:**  
- Ultra-low dropout voltage  
- Low quiescent current for power-sensitive applications  
- Stable with low-ESR ceramic capacitors (≥1µF)  
- Thermal shutdown and current limit protection  
- Reverse current protection  
- Small SOT-223-6 package for space-constrained designs  

This information is sourced from the official TI datasheet for the TPS72518DCQR.
