Description and Introduction

FAST-TRANSIENT-RESPONSE 1-A LOW-DROPOUT LINEAR REGULATORS The TPS76733QDRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 1A  
- **Dropout Voltage:** 350mV (typical) at 1A  
- **Input Voltage Range:** 2.7V to 10V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Package:** SOIC-8 (D)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Features:**  
  - Fast transient response  
  - Thermal shutdown and current limit protection  
  - Stable with low-ESR ceramic capacitors  

### **Descriptions and Features:**  
- The TPS76733QDRG4 is a high-performance LDO regulator designed for applications requiring a stable 3.3V supply.  
- It provides up to 1A of output current with low dropout voltage, making it suitable for battery-powered systems.  
- The device includes built-in protection features such as thermal shutdown and overcurrent protection.  
- It is optimized for use with ceramic output capacitors, reducing board space and cost.  
- Applications include DSPs, FPGAs, and portable electronics.

Application Scenarios & Design Considerations

FAST-TRANSIENT-RESPONSE 1-A LOW-DROPOUT LINEAR REGULATORS

Alternative Part Number

  • LM3940ISX-3.3 --: 3.3V low-dropout linear regulator in SOIC-8 package with similar current capability, pin-compatible enough for many TPS76733QDRG4 applications.
  • MIC29302WU --: Adjustable low-dropout regulator capable of 3A, can be configured for 3.3V output and serves as a robust drop-in replacement in power supply designs.
  • LT1086CM-3.3 --: 3.3V fixed low-dropout regulator with 1.5A output, well-known reliable alternative for 3.3V rail regulation where TI part is unavailable.
