Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High Enable, 250-mA Low Dropout Regulator The TPS79425DGNR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin MSOP (DGNR)  

### **Descriptions:**
- The TPS79425DGNR is a high-performance, low-noise LDO regulator designed for precision power applications.  
- It provides excellent line and load transient response with low dropout voltage.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response**  
- **Thermal Shutdown & Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Enable Pin for Power Management**  

This regulator is ideal for applications requiring stable, low-noise power with minimal dropout voltage.
