Description and Introduction

Fast-Transient-Response 2-A LDO Voltage Regulator The TPS75218QPWPR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 220mV (typical) at 500mA  
- **Input Voltage Range:** 2.5V to 6.5V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 85µA (typical)  
- **Package:** 20-pin HTSSOP (PowerPAD™)  
- **Operating Temperature Range:** -40°C to +125°C  
- **PSRR:** 60dB at 1kHz  
- **Enable Pin:** Yes (active high)  

### **Descriptions and Features:**  
- Designed for low-noise, high-performance applications.  
- Stable with low-ESR ceramic capacitors (≥10µF).  
- Thermal shutdown and current limit protection.  
- PowerPAD™ package for improved thermal performance.  
- Fast transient response for dynamic loads.  
- Low quiescent current for power-sensitive applications.  

This LDO is commonly used in portable electronics, DSPs, FPGAs, and other precision voltage regulation applications.

Application Scenarios & Design Considerations

Fast-Transient-Response 2-A LDO Voltage Regulator

Alternative Part Number

  • LP38692MP-1.8 --: 1.8V fixed LDO in a similar power package with comparable dropout and current capability, suitable drop-in for many TPS75218 applications.
  • MIC29152WT --: Adjustable low-dropout regulator that can be set to 1.8V, offers similar current rating and thermal performance as an alternative from a different vendor.
  • LT1963AEQ-1.8 --: Low-noise 1.8V fixed LDO with comparable dropout voltage and load current, providing a robust cross-vendor replacement option.
