Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High Enable, 250-mA Low Dropout Regulator The TPS79430DCQR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 3.0V (Fixed)  
- **Output Current:** 750mA  
- **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 SON (DCQ)  

### **Descriptions:**  
The TPS79430DCQR is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response. It is optimized for battery-powered systems and provides stable voltage regulation with minimal power dissipation.  

### **Features:**  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 60dB at 1kHz  
- **Enable Pin (EN):** Allows shutdown mode, reducing power consumption  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Fast Transient Response:** Suitable for dynamic loads  

This information is based solely on TI's official datasheet and product documentation.
