Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1A Low Dropout Regulator The TPS79618KTT 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:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 265µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-pin SOT-223 (KTT)  

### **Descriptions:**
- The TPS79618KTT is a high-performance LDO regulator designed for applications requiring low noise and high PSRR.  
- It provides a stable 1.8V output with fast transient response, making it suitable for powering sensitive analog and digital circuits.  
- The device includes thermal shutdown and current limit protection.  

### **Features:**
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 70dB at 1kHz  
- **Fast Transient Response:** Ideal for dynamic loads  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors** (≥1µF)  
- **Low Dropout Voltage:** 110mV (typical) at 500mA  

This regulator is commonly used in portable electronics, RF modules, and precision analog applications.
