Description and Introduction

Ultra Low Noise, High PSRR, Fast RF, High-Enable, 100mA Low Dropout Regulator The TPS79230DBVRG4 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:** 200mA  
- **Dropout Voltage:** 110mV (typical) at 200mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% over line, load, and temperature  
- **Quiescent Current:** 85µA (typical)  
- **Power Supply Ripple Rejection (PSRR):** 60dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS79230DBVRG4 is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and low dropout voltage. It features a low quiescent current, making it suitable for battery-powered devices. The device includes thermal shutdown and current-limit protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** 110mV at 200mA  
- **High PSRR:** 60dB at 1kHz  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response**  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Green Product (RoHS & REACH Compliant)**  

This information is strictly based on the manufacturer's datasheet and specifications.
