Description and Introduction

200mA, Low Quiescent Current, Ultra-Low Noise, High PSRR Low Dropout Linear Regulator 6-WSON -40 to 125 The TPS79918DRVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 200mA  
- **Dropout Voltage:** 110mV (typical) at 200mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±2% over line, load, and temperature  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-pin WSON (DRV)  

### **Descriptions:**
- The TPS79918DRVR is a high-performance LDO regulator designed for low-power applications.  
- It provides a stable 1.8V output with excellent transient response and low noise.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**
- **Ultra-Low Dropout:** Enables operation with very small headroom.  
- **Low Quiescent Current:** Optimized for power-sensitive applications.  
- **High PSRR:** Reduces input noise for cleaner output.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures device safety.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor.  
- **Fast Start-Up Time:** Minimizes delay in power-up sequences.  

This LDO is ideal for applications requiring precise, low-noise voltage regulation in space-constrained designs.
