Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 500mA Low Dropout Regulator The TPS79516DCQ is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.6V (fixed)  
- **Output Current:** 500mA (max)  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 1.1mA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** 6-Pin SOT-223 (DCQ)  

### **Descriptions:**
- The TPS79516DCQ is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response.  
- It provides a fixed 1.6V output with high accuracy (±1.5% over line, load, and temperature).  
- Features thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 75dB at 1kHz  
- **Fast Transient Response:** Ideal for sensitive analog and RF circuits  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Thermal Shutdown & Current Limit Protection**  
- **Low Dropout Voltage:** 110mV (typical) at 500mA  
- **Wide Input Voltage Range (2.5V to 6.5V)**  

This regulator is commonly used in portable electronics, battery-powered devices, and noise-sensitive applications such as RF and precision analog circuits.
