Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125 The TPS71729DCKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 2.9V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 150mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**  
- The TPS71729DCKR is a low-quiescent-current LDO regulator designed for battery-powered applications.  
- It provides stable voltage regulation with low noise and high PSRR.  
- Features a fast transient response and thermal shutdown protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low IQ (Quiescent Current):** Extends battery life in portable applications.  
- **High PSRR:** Reduces noise from input supply variations.  
- **Thermal Shutdown & Current Limit Protection:** Enhances reliability.  
- **Stable with Small Ceramic Capacitors (≥1µF):** Saves board space.
