What are the key features of TPS7A3701DRVT?
- 1% output voltage accuracy over temperature ensures precise regulation for sensitive analog and RF circuits
- Ultra-low 130 mV typical dropout at 1 A output enables near-lossless power conversion from tight supply headroom
- Integrated reverse current protection prevents back-drive damage in multi-rail systems where outputs may be powered out of sequence
What is TPS7A3701DRVT used for?
The TPS7A3701DRVT is well-suited for precision analog power supplies in test and measurement instruments, where its 1% output accuracy and low 0.03 %/V line regulation maintain stable reference voltages. Its reverse current protection makes it safe for hot-plug and sequencing scenarios common in server blade and modular industrial power architectures. The 1 A current capability and 6-pin WSON package combine high performance with minimal PCB footprint for portable and density-critical designs.

Frequently Asked Questions
What is the dropout voltage of TPS7A3701DRVT at full 1 A load, and how does this benefit systems with tight supply budgets?
At 1 A output current, the TPS7A3701DRVT has a typical dropout voltage of 130 mV and a maximum of 200 mV. This allows a 3.3 V output to be derived from a 3.5 V rail with minimal headroom, reducing power dissipation and heat generation in designs where input-to-output differential is constrained.
How does the reverse current protection in TPS7A3701DRVT protect downstream circuitry during power sequencing?
The TPS7A3701DRVT integrates reverse current protection that blocks current from flowing from the output pin back to the input pin, which can occur when multiple supply rails are powered in non-ideal sequences or when the input voltage collapses below the output. This safeguards sensitive loads rated at up to 5.5 V from back-drive conditions without requiring external diodes or additional protection circuitry.
Which precision measurement or RF applications benefit most from the TPS7A3701DRVT 1% accuracy specification?
Applications such as 16-bit or 24-bit ADC reference supplies, precision DAC bias rails, and RF PLL synthesizer VCO supply lines benefit most from the TPS7A3701DRVT 1% initial accuracy. Even over the full -40°C to 125°C operating temperature range, tight output accuracy reduces calibration overhead and avoids the gain errors that would otherwise require correction in high-resolution measurement chains.
What package does TPS7A3701DRVT use and how does it compare dimensionally to an SOT-23-5?
The TPS7A3701DRVT uses a 6-pin WSON (S-PDSO-N6) package measuring approximately 2 mm × 2 mm, which is smaller than the typical SOT-23-5 footprint of 2.9 mm × 1.6 mm when pin clearance is included. The exposed thermal pad also improves heat spreading at 1 A output current, enabling operation without a heatsink in most applications where θJA is around 50°C/W.
