Description and Introduction

Fast Transient Response 250-mA LDO Voltage Regulator W/Power Good, MSOP-8 Packaging The TPS77401DGKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Output Voltage:** Fixed 1.8V (other variants available in the series).  
- **Output Current:** Up to 500mA.  
- **Dropout Voltage:** 300mV (typical) at 500mA load.  
- **Input Voltage Range:** 2.7V to 5.5V.  
- **Accuracy:** ±2% over line, load, and temperature.  
- **Quiescent Current:** 85µA (typical).  
- **Package:** 8-pin VSSOP (DGK).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **PSRR:** 60dB at 1kHz.  

### **Descriptions:**
The TPS77401DGKR is a high-performance LDO regulator designed for low-power applications. It provides a stable 1.8V output with low noise and high power-supply rejection ratio (PSRR), making it suitable for noise-sensitive applications like analog and RF circuits.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation with minimal headroom.  
- **Low Quiescent Current:** Ideal for battery-powered devices.  
- **Thermal and Overcurrent Protection:** Safeguards against excessive heat and current.  
- **Stable with Ceramic Capacitors:** Works with small, low-ESR capacitors.  
- **Fast Transient Response:** Maintains stability under dynamic load conditions.  
- **Enable Pin:** Allows power management control.
