Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125 The TPS71728DCKR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 150mA (maximum)  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Quiescent Current:** 17µA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**  
- The TPS71728DCKR is a low-power, low-dropout linear regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low noise and high PSRR (Power Supply Rejection Ratio).  
- Features thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **High PSRR:** 60dB at 1kHz (typical), reducing noise in sensitive circuits.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards the device from overheating and overcurrent conditions.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count and cost.  
- **Small Package (SC-70):** Suitable for space-constrained PCB designs.  

This information is sourced from the official Texas Instruments datasheet for the TPS71728DCKR.
