Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 6-WSON -40 to 125 The TPS71745DSER is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 4.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 150mV (typical) at 150mA load  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 16µA (typical)  
- **Package:** 5-pin SOT-23 (DSER)  

### **Descriptions:**
- The TPS71745DSER is a low-power, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable 4.5V output with high PSRR (Power Supply Rejection Ratio) and low noise.  
- Features thermal shutdown and current limit protection.  

### **Features:**
- **Ultra-Low Quiescent Current:** 16µA (typical) for improved battery life.  
- **Low Dropout Voltage:** 150mV (typical) at full load.  
- **High PSRR:** 70dB at 1kHz for noise-sensitive applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors ≥1µF.  
- **Protection Features:** Thermal shutdown and current limit.  
- **Wide Operating Temperature Range:** -40°C to +125°C.  

This information is strictly factual from TI's datasheet and product documentation.
