Description and Introduction

250mA, Low Quiescent Current, Ultra-Low Noise, High PSRR, Low-Dropout Linear Regulator 5-SOT -40 to 125 The TPS73433DDCR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 110mV (typical) at 250mA  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 75µA (typical)  
- **Package:** SOT-23-5 (DDC)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  

### **Descriptions:**  
The TPS73433DDCR is a low-noise, high-PSRR LDO regulator designed for battery-powered and noise-sensitive applications. It provides a stable 3.3V output with low dropout and low quiescent current, making it suitable for portable electronics.  

### **Features:**  
- **Low Dropout:** 110mV typical at 250mA  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **High PSRR:** 75dB at 1kHz  
- **Fast Transient Response**  
- **Thermal and Overcurrent Protection**  
- **Stable with Low-ESR Ceramic Capacitors (≥1µF)**  
- **Enable Pin for Power Management**  

This information is based solely on the manufacturer's datasheet.
