Description and Introduction

Ultralow-Power, Low-Noise 50-mA Low Dropout (LDO) Linear Regulator The TPS79030DBVRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.3%/mA (typical)  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS79030DBVRG4 is a low-noise, high-PSRR (Power Supply Rejection Ratio) LDO regulator designed for battery-powered and noise-sensitive applications. It provides a stable 3.0V output with low dropout voltage and ultra-low quiescent current, making it suitable for portable electronics.  

### **Features:**  
- **High PSRR:** 70dB at 1kHz  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response**  
- **Thermal Shutdown & Overcurrent Protection**  
- **Enable Pin (Active High) for Power Management**  
- **Stable with Ceramic Capacitors (≥1µF)**  

This device is commonly used in portable devices, medical equipment, and precision analog circuits.
