Description and Introduction

Single Output LDO, 400mA, Adj.(1.2 to 5.5V), Cap free, Low Noise, Reverse Current Protection 5-SOT-23 -40 to 125 The TPS73643DBVRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 4.3V (fixed)  
- **Output Current:** 400mA  
- **Dropout Voltage:** 110mV (typical) at 300mA  
- **Input Voltage Range:** 2.2V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **PSRR:** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TPS73643DBVRG4 is a low-noise, high-PSRR LDO regulator designed for battery-powered applications.  
- It offers a stable output with low dropout voltage, making it suitable for power-sensitive designs.  
- Includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Dropout:** Enables efficient operation with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **High PSRR:** Provides excellent line transient rejection.  
- **Enable Pin:** Allows for power-saving shutdown mode.  
- **Thermal & Current Protection:** Safeguards against overheating and overcurrent conditions.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor for stability.  

This information is sourced from TI's official datasheet for the TPS73643DBVRG4.
