- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/A (typical)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223-6 (DCQ)  

### **Descriptions:**  
- The TPS79533DCQR is a high-performance LDO regulator designed for low-noise, high-precision applications.  
- It provides a stable 3.3V output with excellent transient response and low dropout voltage.  
- Suitable for battery-powered and noise-sensitive applications such as RF, medical, and industrial systems.  

### **Features:**  
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response**  
- **Thermal Shutdown & Current Limit Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Low Quiescent Current for Power Efficiency**  
- **High PSRR for Noise-Sensitive Applications**
