Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1.5A Low Dropout Regulator The TPS78628KTT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Fixed 2.8V  
- **Output Current:** Up to 1.5A  
- **Dropout Voltage:** 340mV (typical) at 1.5A  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 1.2mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-Pin TO-263 (KTT)  

### **Descriptions:**
- The TPS78628KTT is a high-performance LDO regulator designed for applications requiring precise voltage regulation with low noise and high PSRR (Power Supply Rejection Ratio).  
- It features fast transient response and stable operation with small ceramic capacitors.  
- The device includes thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **High PSRR:** 75dB at 1kHz  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Fast Transient Response**  
- **Thermal Shutdown and Overcurrent Protection**  
- **Stable with Ceramic Capacitors (≥10µF)**  
- **Enable Pin for Power Management**  

This LDO is commonly used in power-sensitive applications such as portable devices, networking equipment, and industrial systems.
