Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-DSBGA -40 to 125 The TPS79928YZUR 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  
- **Dropout Voltage:** 110mV (typical at 200mA load)  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **Package:** 5-Pin SOT-23 (YZU)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR (Power Supply Rejection Ratio):** 60dB (at 1kHz)  

### **Descriptions:**
- The TPS79928YZUR is a low-noise, low-dropout linear regulator designed for battery-powered and noise-sensitive applications.  
- It provides a stable 2.8V output with high accuracy and low quiescent current, making it suitable for portable and power-sensitive devices.  
- The device includes features like thermal shutdown and current limiting for protection.  

### **Features:**
- **Ultra-Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown & Current Limit Protection:** Safeguards the device under fault conditions.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor for stability.  
- **Fast Transient Response:** Ensures stable performance under dynamic load conditions.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to TI's official documentation.
