Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125 The TPS71728DCKRG4 is a low-dropout (LDO) linear 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:** 2.8V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 150mV (typical at 100mA load)  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Shutdown Current:** <1µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 60dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**  
- The TPS71728DCKRG4 is a low-noise, high-PSRR LDO regulator designed for battery-powered applications.  
- It provides a stable 2.8V output with low dropout voltage, making it suitable for power-sensitive designs.  
- Features thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **High PSRR:** Reduces input ripple for cleaner output.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent conditions.  
- **Wide Operating Temperature Range:** Suitable for industrial and automotive applications.  
- **Small Package (SC-70):** Ideal for space-constrained designs.  

This information is sourced from the official Texas Instruments datasheet for the TPS71728DCKRG4.
