Description and Introduction

Ultra-Low-Quiescent-Current 150-mA LDO Linear Regulators The TPS76550DR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 35mV (typical) at 10mA load  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Package:** SOIC-8 (DR)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The TPS76550DR is a low-power LDO regulator designed for battery-powered applications. It provides stable 5V output with low dropout voltage and minimal quiescent current, making it suitable for portable devices.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards against overheating and overcurrent.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum capacitors.  
- **Fast Transient Response:** Maintains stable output under varying load conditions.
