Description and Introduction

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1A Low Dropout Regulator The TPS79630KTTR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 500mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% over line, load, and temperature  
- **Quiescent Current:** 265µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 5-pin SOT-23 (KTTR)  

### **Descriptions:**
The TPS79630KTTR is a high-performance LDO regulator designed for applications requiring low noise, high PSRR, and fast transient response. It features a low dropout voltage and stable operation with small ceramic capacitors.  

### **Features:**
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 75dB at 1kHz  
- **Fast Transient Response**  
- **Thermal Shutdown & Overcurrent Protection**  
- **Stable with 1µF or Larger Ceramic Capacitors**  
- **Low Quiescent Current (265µA typical)**  

This device is commonly used in portable electronics, battery-powered systems, and noise-sensitive applications.

Application Scenarios & Design Considerations

Ultra-Low Noise, High PSRR, Fast RF, High-Enable, 1A Low Dropout Regulator

Alternative Part Number

  • LP38693SD-3.0/NOPB --: Low-dropout 3.0V linear regulator in a similar power package with comparable current capability and low noise, suitable as a direct functional substitute.
  • ADP3338AKC-3.0-R7 --: 3.0V low-dropout regulator with low noise and good PSRR, offering similar performance for analog and mixed-signal supply rails.
  • MIC39100-3.0WS --: 3.0V LDO regulator with low dropout and stable output, a practical alternative when the original TI part is unavailable.
