Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1A Low Dropout Regulator The TPS79633KTTT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
TPS79633KTTT  

### **Description:**  
The TPS79633KTTT is a high-performance, low-dropout (LDO) linear voltage regulator designed to provide a fixed output voltage of **3.3V** with high accuracy, low noise, and excellent transient response.  

### **Key Features:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to **500mA**  
- **Dropout Voltage:** **150mV (typical) at 500mA load**  
- **High PSRR (Power Supply Rejection Ratio):** **75dB at 1kHz**  
- **Low Noise:** **30μVRMS (10Hz to 100kHz)**  
- **Input Voltage Range:** **2.7V to 5.5V**  
- **Low Quiescent Current:** **265μA (typical)**  
- **Thermal Shutdown & Overcurrent Protection**  
- **Stable with Small Ceramic Capacitors (≥1μF)**  
- **Package:** **SOT-223 (KTTT)**  

### **Applications:**  
- Portable and battery-powered devices  
- RF and precision analog circuits  
- Noise-sensitive applications (e.g., audio, medical)  
- Post-regulation for switching power supplies  

This information is sourced from Texas Instruments' official datasheet for the TPS79633KTTT.
