Description and Introduction

50-mA, 5.0-V High Input-Voltage LDO Voltage Regulator in SC-70 The TPS71550QDCKRQ1 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 6.5V  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**  
The TPS71550QDCKRQ1 is an automotive-qualified, low-power LDO regulator designed for applications requiring stable voltage with minimal power consumption. It features low dropout voltage, low quiescent current, and high PSRR (Power Supply Rejection Ratio), making it suitable for battery-powered and noise-sensitive systems.  

### **Features:**  
- **Low Dropout Voltage:** 300mV typical at 150mA  
- **Ultra-Low Quiescent Current:** 17µA (typical)  
- **High PSRR:** 75dB at 1kHz  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors**  
- **AEC-Q100 Qualified for Automotive Applications**  
- **Wide Operating Temperature Range:** -40°C to +125°C  

This device is ideal for automotive, industrial, and portable electronics requiring reliable voltage regulation.
