Description and Introduction

Single Output LDO, 1A, Adj. (1.2 to 5.0V), Reverse Current Protection 6-SOT-223 -40 to 125 The TPS73718DCQR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 110mV (typical) at 100mA load  
- **Input Voltage Range:** 2.2V to 6V  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Pin SOT-223 (DCQ)  

### **Descriptions:**  
The TPS73718DCQR is a low-noise, high-PSRR LDO regulator designed for applications requiring stable voltage with minimal power loss. It features a low dropout voltage, making it suitable for battery-powered devices. The device includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Optimized for battery-powered applications.  
- **High PSRR:** Improves noise rejection in sensitive circuits.  
- **Low Quiescent Current:** Enhances efficiency in power-sensitive designs.  
- **Thermal Shutdown & Current Limit Protection:** Ensures safe operation.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.  
- **Fixed Output Voltage:** 1.8V (no external resistors needed).  

This information is strictly factual from Ic-phoenix technical data files. No additional guidance or suggestions are included.

Alternative Part Number

  • LP38692SD-1.8 --: 1.8V fixed LDO in a similar SOT-223/TO-252 style package with comparable current capability, suitable drop-in for many TPS73718 applications.
  • MIC5219-1.8YM5 --: 1.8V fixed low-dropout regulator with low noise and good PSRR, an alternative topology and different series from the source.
  • AP2112K-1.8TRG1 --: 1.8V fixed LDO with low quiescent current in a small package, a cost-effective alternative for light-load 1.8V regulation.
  • LP38693SD-1.8/NOPB --: 1.8V fixed LDO in a similar SOT-223 style package with comparable dropout and current capability, from the same vendor for easy qualification.
  • ADP1712AUJZ-1.8-R7 --: 1.8V fixed low-dropout regulator in TSOT package, offering similar load current and low noise performance as a cross-vendor alternative.
  • MIC5219-1.8YM5-TR --: 1.8V fixed LDO regulator with low dropout and compact SOT-23-5 package, suitable for space-constrained designs needing a different supplier.
