Description and Introduction

ULTRALOW-NOISE, HIGH PSRR, FAST RF 500-mA LOW-DROPOUT LINEAR REGULATORS The TPS79501 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 340mV (typical at 500mA load)  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.04%/mA (typical)  
- **Quiescent Current:** 85µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** 5-pin SOT-23 (DBV)  

### **Descriptions:**  
The TPS79501 is a high-performance, low-noise LDO regulator designed for applications requiring precise voltage regulation with minimal power dissipation. It features fast transient response, excellent PSRR, and low quiescent current, making it suitable for battery-powered and noise-sensitive systems.  

### **Features:**  
- **Ultra-Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High Accuracy:** ±1.5% output voltage tolerance  
- **Fast Transient Response**  
- **Thermal and Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Enable Pin for Power Management**
