Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1.5A Low Dropout Regulator The TPS78625KTTT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 1.5A  
- **Dropout Voltage:** 340mV (typical) at 1.5A  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Accuracy:** ±2% over line, load, and temperature  
- **Quiescent Current:** 1mA (typical)  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** 5-pin TO-263 (KTTT)  

### **Descriptions:**
- The TPS78625KTTT is a high-performance LDO regulator designed for applications requiring high current and low dropout voltage.  
- It features fast transient response and excellent line/load regulation.  
- Includes built-in thermal shutdown and current-limit protection.  

### **Features:**
- **Low Dropout:** 340mV (typical) at full load  
- **High PSRR:** 75dB at 1kHz  
- **Thermal Shutdown Protection:** Prevents damage from overheating  
- **Current Limit Protection:** Safeguards against excessive current  
- **Stable with Ceramic Capacitors:** Requires only a 10µF output capacitor  
- **Fast Transient Response:** Suitable for dynamic load applications
