Key Features
- 5 A output current with only 75 mV typical dropout voltage minimizes power loss in high-current rails
- Ultra-low input voltage range starting at 0.7 V enables use in sub-1 V power delivery architectures
- High-accuracy adjustable output with low-noise performance ideal for sensitive RF and analog loads
- Compact 16-pin QFN (S-PQCC-N16) package reduces board footprint in space-constrained designs
- RoHS-compliant (e4) Pb-free construction meets modern environmental requirements
Applications
The TPS7A5701RTER is well suited for powering noise-sensitive analog and RF circuits in wireless infrastructure, test and measurement equipment, and high-performance computing boards where a clean 5 A supply rail is essential. Its 0.7 V to 6 V input range and 75 mV typical dropout make it an efficient post-regulator after a switching converter, reducing ripple without sacrificing headroom. It is also used in portable industrial instruments and FPGA core supplies where high output current accuracy and low noise floor directly affect system performance.

Frequently Asked Questions
What is the maximum output current the TPS7A5701RTER can deliver, and what dropout voltage should I budget?
The TPS7A5701RTER delivers up to 5 A of continuous output current. Its typical dropout voltage is only 75 mV at full load, with a maximum specified value of 110 mV, so a 6 V input rail can regulate down to outputs well above 5.9 V without losing regulation.
Why is the TPS7A5701RTER a good post-regulator after a switching converter in an RF system?
Its high-accuracy adjustable output and low-noise LDO architecture suppress switching-converter ripple on the final supply rail. With an input range starting as low as 0.7 V and a 75 mV typical dropout, the regulator adds minimal headroom overhead while delivering up to 5 A to sensitive RF front-end or ADC circuits that require a clean power supply.
Which package does the TPS7A5701RTER use, and how does it aid thermal management?
The TPS7A5701RTER ships in a 16-pin QFN package (JESD-30 code S-PQCC-N16) with an exposed thermal pad on the bottom, enabling direct heat transfer to the PCB copper pour. This allows efficient dissipation of the power loss (V_dropout × 5 A) through standard PCB vias and copper pours without an external heatsink.
How does TPS7A5701RTER compare to a multi-amp switching regulator for FPGA core voltage supply?
For FPGA core rails that demand low noise below 100 mV ripple and currents up to 5 A, the TPS7A5701RTER outperforms switching regulators in noise performance because it has no switching artifacts. The trade-off is efficiency: at 6 V input and 1 V output, the 75 mV dropout still means roughly 1 W dissipated at full 5 A load, which is manageable in most FPGA power designs.
