Description and Introduction

Low Input Voltage, Any Cap, 1-A Low-Dropout Linear Regulator with Supervisor The TPS72518DCQ is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 170mV (typical) at 500mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 17µA (typical)  
- **Package:** 6-Pin SOT-223 (DCQ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% over line, load, and temperature  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Enable Pin:** Yes (active high)  

### **Descriptions:**  
The TPS72518DCQ is a low-dropout linear regulator designed for applications requiring a stable 1.8V supply. It features low quiescent current, making it suitable for battery-powered devices. The regulator includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **Enable Pin:** Allows for power-saving modes.  
- **High PSRR:** Provides excellent noise rejection.
