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 TPS74401RGWT 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:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 4A  
- **Dropout Voltage:** 85mV (typical) at 1A load  
- **Accuracy:** ±1% over line, load, and temperature  
- **Quiescent Current:** 40µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin VQFN (RGWT)  

### **Descriptions:**
- The TPS74401RGWT is a high-performance, low-dropout linear regulator designed for high-current applications.  
- It features excellent transient response and low noise, making it suitable for powering sensitive analog and digital loads.  
- The device includes integrated power MOSFETs, current limiting, and thermal shutdown for protection.  

### **Features:**
- **Ultra-Low Dropout Voltage:** Enables efficient operation with very small headroom.  
- **High PSRR:** 60dB at 1kHz for noise-sensitive applications.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Power Good (PG) Indicator:** Monitors output voltage status.  
- **Adjustable Output Voltage:** Set via external resistor divider.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation under fault conditions.  
- **Low Quiescent Current:** Improves efficiency in battery-powered applications.
