Description and Introduction

Single Output LDO, 3.0A, Adj.(0.8 to 3.3V), Fast Transient Response, Programmable Soft Start 20-VQFN -40 to 125 The TPS74401RGWR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 1.4V to 6.5V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Output Current:** Up to 4A  
- **Dropout Voltage:** 85mV (typical) at 1A load  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 40µA (typical)  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin VQFN (RGWR)  

### **Descriptions:**
- The TPS74401 is a high-performance, low-dropout linear regulator designed for applications requiring high efficiency and precision.  
- It features a low quiescent current and excellent transient response, making it suitable for powering low-voltage processors, FPGAs, and ASICs.  
- The device includes integrated power-good (PG) monitoring and soft-start functionality.  

### **Features:**
- **High Efficiency:** Low dropout voltage minimizes power loss.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Power-Good (PG) Output:** Monitors regulator status.  
- **Wide Input Voltage Range:** Supports various power sources.  
- **Thermal Shutdown & Overcurrent Protection:** Enhances reliability.  
- **Low Noise & High PSRR:** Suitable for noise-sensitive applications.
