Description and Introduction

50-mA, 5.0-V High Input-Voltage LDO Voltage Regulator in SC-70 The TPS71550DCKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 340mV (typical) at 150mA  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Quiescent Current:** 85µA (typical)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**
- The TPS71550DCKR is a low-power LDO regulator designed for battery-powered applications.  
- It provides a stable 5V output with low dropout voltage, making it suitable for systems with tight voltage margins.  
- Features low quiescent current, enhancing efficiency in portable devices.  

### **Features:**
- **Low Dropout Voltage:** Ensures stable operation even with small input-output differentials.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  

This regulator is commonly used in portable electronics, IoT devices, and other low-power applications requiring a stable 5V supply.
