Description and Introduction

Single Output LDO, 3.0A, Adj.(0.8 to 3.3V), Fast Transient Response, Programmable Soft Start 7-DDPAK/TO-263 -40 to 125 The TPS74401 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 0.8V to 5.5V (adjustable)  
- **Output Current:** 4A (maximum)  
- **Dropout Voltage:** 85mV (typical) at 1A load  
- **Input Voltage Range:** 1.4V to 6.5V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 1.1mA (typical)  
- **Power Good (PG) Threshold:** Adjustable  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5mm × 5mm VQFN (RGW)  

### **Descriptions:**
- The TPS74401 is a high-performance, low-dropout linear regulator designed for applications requiring high efficiency and precise voltage regulation.  
- It integrates a PMOS pass transistor for low dropout and high current capability.  
- The device includes a power-good (PG) indicator for system monitoring.  

### **Features:**
- **Ultra-Low Dropout:** Enables efficient operation with minimal headroom.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Programmable Soft Start:** Reduces inrush current during startup.  
- **Thermal Shutdown & Overcurrent Protection:** Enhances reliability.  
- **Low Noise & High PSRR:** Suitable for noise-sensitive applications.  
- **Small Footprint:** 5mm × 5mm VQFN package for space-constrained designs.
