Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1.5A Low Dropout Regulator The TPS78625DCQR 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 (maximum)  
- **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:** 1.1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-pin SOT-223 (DCQ)  

### **Descriptions:**
- The TPS78625DCQR is a high-performance LDO regulator designed for applications requiring high accuracy and low noise.  
- It provides a fixed 2.5V output with excellent line and load transient response.  
- Features thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **High PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz (improves noise immunity).  
- **Fast Transient Response:** Suitable for dynamic load conditions.  
- **Thermal Shutdown & Current Limit Protection:** Protects the device from overheating and overcurrent.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **Low Noise Output:** Ideal for noise-sensitive applications.  

This information is based on the manufacturer's datasheet and technical documentation.
