Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 250mA Low Dropout Regulator The TPS79418DCQ is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-pin SON (DCQ)  

### **Descriptions:**  
- The TPS79418DCQ is a high-performance, low-noise LDO regulator designed for applications requiring precise voltage regulation.  
- It features fast transient response and excellent line/load regulation.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Enable Pin:** Allows shutdown mode, reducing current consumption to <1µA.  
- **Thermal Shutdown & Current Limit Protection:** Ensures safe operation under fault conditions.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF (or greater) output capacitor.  
- **Small Footprint:** 6-pin SON package (2mm × 2mm) for space-constrained designs.
