Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 5-DSBGA -40 to 125 The TPS79918YZUR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.8 V (fixed)  
- **Output Current:** 200 mA  
- **Dropout Voltage:** 110 mV (typical at 200 mA)  
- **Input Voltage Range:** 2.5 V to 6.5 V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17 µA (typical)  
- **PSRR:** 60 dB (at 1 kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-pin SOT-23 (YZU)  

### **Descriptions:**
- The TPS79918YZUR is a high-performance, low-noise LDO regulator designed for battery-powered and noise-sensitive applications.  
- It provides a stable 1.8 V output with excellent line and load transient response.  
- Features reverse current protection and thermal shutdown for reliability.  

### **Features:**
- **Low Noise:** 30 µVRMS (10 Hz to 100 kHz)  
- **High PSRR:** 60 dB at 1 kHz  
- **Low Dropout Voltage:** 110 mV (typical at 200 mA)  
- **Low Quiescent Current:** 17 µA (typical)  
- **Fast Start-Up Time:** ~50 µs  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Small Ceramic Capacitors (≥1 µF)**  

This LDO is suitable for applications such as portable electronics, medical devices, and precision analog circuits.
