Description and Introduction

Ultra Low Noise, High PSRR, Fast RF, High-Enable, 100mA Low Dropout Regulator The TPS79228DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 200mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Dropout Voltage:** 150mV (typical) at 200mA load  
- **Accuracy:** ±1% (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:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS79228DBVR is a high-performance, low-noise, low-dropout linear regulator designed for battery-powered and noise-sensitive applications. It provides a stable 2.8V output with excellent line and load transient response.  

### **Features:**  
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Start-Up Time:** ~50µs  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Enable Pin for Power Management**  

This regulator is commonly used in portable electronics, RF/wireless systems, and precision analog circuits.
