Description and Introduction

Low-Noise, High PSRR, RF 200-mA Low-Dropout Linear Regulators 5-SOT-23 -40 to 85 The TPS73047DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 4.7V (fixed)  
- **Output Current:** 250mA  
- **Input Voltage Range:** 2.2V to 6.5V  
- **Dropout Voltage:** 85mV (typical) at 250mA load  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 30µA (typical)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS73047DBVT is a low-noise, high-PSRR LDO regulator designed for battery-powered applications.  
- It provides a stable 4.7V output with low dropout and minimal power dissipation.  
- Features an enable pin (EN) for power-saving mode.  

### **Features:**  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 70dB at 1kHz  
- **Thermal and Overcurrent Protection**  
- **Fast Transient Response**  
- **Stable with Small Ceramic Capacitors (1µF or larger)**  

This regulator is suitable for portable electronics, IoT devices, and other power-sensitive applications.
