Description and Introduction

Low Input Voltage, 1-A Low-Dropout Linear Regulators with Supervisor 6-SOT-223 -40 to 125 The TPS72518DCQRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 300mV (typical) at 500mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** SOT-223-5 (DCQ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Thermal shutdown, current limit, reverse current protection  

### **Descriptions and Features:**  
- **Low Dropout:** Ensures stable operation even when input voltage is close to the output voltage.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF (or larger) output capacitor for stability.  
- **High PSRR:** Good noise rejection for sensitive applications.  
- **Thermal Shutdown and Current Limit:** Protects the device from overheating and overcurrent conditions.  
- **Reverse Current Protection:** Prevents damage from reverse current flow.  

This regulator is suitable for portable electronics, industrial, and automotive applications requiring a stable 1.8V supply.
