Description and Introduction

Ultralow-Noise, High-PSRR, Fast, 250-mA Low-Dropout Linear Regulators 8-MSOP-PowerPAD -40 to 85 The TPS79425DGNRG4 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:** 750mA  
- **Dropout Voltage:** 110mV (typical at 500mA)  
- **Input Voltage Range:** 2.7V to 6.5V  
- **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:** 8-Pin MSOP (DGNR)  

### **Descriptions:**
- The TPS79425DGNRG4 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.  
- It features a low-dropout voltage, making it suitable for battery-powered devices.  
- Includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 60dB at 1kHz  
- **Fast Transient Response**  
- **Enable Pin (EN) for Power Management**  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**

- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin MSOP (DGNR)  

### **Descriptions:**
- The TPS79425DGNRG4 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.  
- It features a low dropout voltage and stable operation with small ceramic capacitors.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 70dB at 1kHz  
- **Enable Pin (EN):** Allows shutdown mode, reducing current consumption to <1µA  
- **Thermal Shutdown & Overcurrent Protection:** Ensures device safety  
- **Stable with Ceramic Capacitors:** 4.7µF or larger  

This LDO is ideal for powering sensitive analog and digital circuits where stable voltage regulation is critical.
