Description and Introduction

200mA Low Quiescent Current, Ultra-Low Noise, High PSRR LDO The TPS79901DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Output Voltage:** Fixed 1.8V  
- **Output Current:** 200mA  
- **Dropout Voltage:** 175mV (typical) at 200mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% over line, load, and temperature  
- **Quiescent Current:** 17µA (typical)  
- **PSRR:** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DDC)  

### **Descriptions:**  
The TPS79901DDCR is a high-performance, low-dropout linear regulator designed for power-sensitive applications. It provides a stable 1.8V output with low noise and high power-supply rejection ratio (PSRR), making it suitable for battery-powered devices, portable electronics, and noise-sensitive analog circuits.  

### **Features:**  
- **Low Dropout:** 175mV typical at full load  
- **Low Quiescent Current:** 17µA (improves battery life)  
- **High PSRR:** 75dB at 1kHz (rejects input noise effectively)  
- **Thermal Shutdown & Overcurrent Protection:** Ensures device safety  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces board space and cost  
- **Fast Transient Response:** Suitable for dynamic loads  

This information is based solely on TI's official datasheet for the TPS79901DDCR.
