Description and Introduction

Ultralow-Noise, High-PSRR, Fast, 250-mA Low-Dropout Linear Regulators 8-MSOP-PowerPAD -40 to 85 The TPS79433DGNRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 750mA  
- **Dropout Voltage:** 110mV (typical) at 500mA load  
- **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:** 8-Pin HVSSOP (DGNR)  

### **Descriptions:**
- The TPS79433DGNRG4 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 systems.  
- The device includes thermal shutdown and overcurrent protection for reliability.  

### **Features:**
- **High PSRR:** Ensures stable output under varying input conditions.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Fast Transient Response:** Maintains stable output during load changes.  
- **Thermal Shutdown & Overcurrent Protection:** Enhances device safety.  
- **Enable Pin:** Allows for power-saving modes when disabled.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  

This LDO is commonly used in portable electronics, RF/mixed-signal circuits, and power-sensitive applications.
