Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High Enable, 250-mA Low Dropout Regulator The TPS79425DCQ is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V 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:** 6-pin SOT-223 (DCQ)  

### **Descriptions:**  
The TPS79425DCQ is a high-performance LDO regulator designed for low-power applications requiring precise voltage regulation. It features low noise, high PSRR, and fast transient response, making it suitable for sensitive analog and digital circuits.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **High PSRR:** Minimizes output ripple from input variations.  
- **Thermal and Overcurrent Protection:** Safeguards the device under fault conditions.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces board space and cost.  
- **Fast Transient Response:** Maintains stable output under load changes.  

This regulator is commonly used in portable electronics, battery-powered devices, and precision analog circuits.  

(Note: All details are based on TI's official datasheet and product documentation.)
