Description and Introduction

Single Output LDO, 500mA, Adj. (0.8 to 3.6V), Programmable Soft-Start 10-VSON -40 to 125 The TPS74701DRCRG4 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI).  

**Specifications:**  
- **Input Voltage Range:** 1.4V to 6.5V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Output Current:** 3A  
- **Dropout Voltage:** 150mV (typical) at 3A  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 40µA (typical)  
- **Operating Junction Temperature Range:** -40°C to +125°C  
- **Package:** VSON-10 (DRC)  

**Descriptions:**  
The TPS74701 is a high-performance LDO regulator designed for applications requiring low input voltage and high output current. It features excellent transient response, low noise, and high PSRR (Power Supply Rejection Ratio).  

**Features:**  
- Adjustable output voltage via external resistors  
- Low dropout voltage for high efficiency  
- Stable with ceramic output capacitors  
- Integrated soft-start for controlled inrush current  
- Thermal shutdown and overcurrent protection  
- Enable pin for power sequencing  

This information is based on TI's official datasheet for the TPS74701DRCRG4.

Application Scenarios & Design Considerations

Single Output LDO, 500mA, Adj. (0.8 to 3.6V), Programmable Soft-Start 10-VSON -40 to 125

Alternative Part Number

  • TPS74701DRCR --: Same TPS74701 adjustable LDO regulator in the same 10-pin VSON package, identical electrical specifications; the G4 suffix is only a lead-free/RoHS designation, so this is a drop-in replacement.
  • TPS74801DRCR --: Very similar TI adjustable LDO in the same VSON-10 package with comparable dropout and current rating; a close functional substitute from the same family with slightly different bias/feedback requirements.
  • TPS7A7001DRCR --: TI adjustable low-dropout regulator in the same VSON-10 footprint, offering similar output current and dropout performance as an alternative source for the same board position.
