What are the key features of TPS7A7401DSDR?
- 1.5 A continuous output current with only 0.15 V typical dropout voltage, minimizing power dissipation in battery-powered and efficiency-sensitive designs
- Programmable soft-start function reduces inrush current during power-up, protecting downstream capacitors and load circuits
- Wide input voltage range of 0.8 V to 6 V with adjustable output supports diverse supply-rail architectures in industrial and consumer systems
What is TPS7A7401DSDR used for?
TPS7A7401DSDR suits post-regulation stages in DDR memory supplies, FPGAs, and DSP core rails where tight output accuracy and low noise are critical. Its programmable soft-start and 1.5 A current capability make it a natural fit for solid-state drive power trees and portable instrumentation. The part also works well in wearable medical devices and IoT sensor nodes that demand low quiescent current and compact footprint.

Frequently Asked Questions
What dropout voltage does TPS7A7401DSDR exhibit at full 1.5 A load?
At the maximum 1.5 A output current, TPS7A7401DSDR typically exhibits a dropout voltage of 0.15 V and no more than 0.18 V worst case, enabling efficient regulation from rails as close as 200 mV above the set output—ideal for 1.8 V or 3.3 V supply domains.
How do you configure the soft-start time on TPS7A7401DSDR to limit inrush current during power-up?
Soft-start duration is set with a single external capacitor on the SS pin; larger capacitance extends the ramp from 0 V to the target output, typically in the range of 1 ms to 50 ms, reducing inrush current below the 1.5 A steady-state rating and protecting bulk capacitors downstream.
Which supply-rail scenarios make TPS7A7401DSDR a better choice than a fixed-output LDO?
When the design requires an adjustable output between 0.8 V and 5.8 V—such as core rails for FPGAs that vary by speed grade—TPS7A7401DSDR offers flexibility unavailable in fixed regulators. Its 0.05 %/V line regulation and 1.5 A capability cover most FPGA and DSP core requirements in a single 8-pin SON footprint of approximately 2 mm × 2 mm.
