Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125 The TPS71719DCKR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.9V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical at 150mA load)  
- **Input Voltage Range:** 2.2V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (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 TPS71719DCKR is a low-power, low-dropout linear regulator designed for battery-powered and portable applications.  
- It provides stable voltage regulation with low noise and high PSRR, making it suitable for noise-sensitive circuits.  
- 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 devices.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Thermal Shutdown & Current Limit Protection:** Safeguards against overheating and overcurrent conditions.  
- **Fast Transient Response:** Maintains stable output under dynamic load conditions.  

This regulator is commonly used in applications such as portable electronics, IoT devices, and power-sensitive systems.
