Key Features
- Fixed 3.3 V output with 170 mV typical dropout voltage enables efficient regulation from 3.5 V Li-ion or 5 V USB rails
- 1 A continuous output current in a compact VSON-8 (S-PDSO-N8) package minimizes PCB area for space-constrained designs
- Wide 3.8 V to 6.5 V input range with 15+ year product lifecycle ensures design longevity in industrial and communications hardware
Applications
TPS7A8033DRBT is ideal for powering microcontrollers, FPGAs, and RF transceivers that require a stable 3.3 V supply derived from 5 V USB or a single-cell Li-ion battery. Its low 170 mV dropout voltage ensures the regulator stays in regulation even as the battery discharges toward 3.5 V, maximizing usable capacity. The VSON-8 footprint suits dense IoT sensor nodes, wearables, and portable industrial instruments.

Frequently Asked Questions
What input voltage range and dropout voltage does TPS7A8033DRBT support?
TPS7A8033DRBT operates from a 3.8 V minimum to 6.5 V maximum input voltage with a typical dropout voltage of only 170 mV at 1 A. This low dropout allows it to regulate a 3.3 V output from a nearly depleted single-cell Li-ion battery or directly from a 5 V USB supply with minimal power loss.
How much output current can TPS7A8033DRBT deliver for powering a 3.3 V microcontroller rail?
TPS7A8033DRBT delivers up to 1 A continuously on its fixed 3.3 V output, which is sufficient to power a 32-bit microcontroller core, its peripherals, and several attached sensors simultaneously. The maximum 0.5 V dropout at full 1 A load ensures stable regulation down to about 3.8 V input without requiring an additional boost stage.
Which package does TPS7A8033DRBT use and how does it affect PCB thermal design?
TPS7A8033DRBT comes in a VSON-8 (S-PDSO-N8) surface-mount package, which includes an exposed thermal pad that significantly reduces junction-to-board thermal resistance compared to standard SOIC packages. Connecting this pad to a copper pour with multiple thermal vias allows the 1 A device to operate well below its thermal shutdown threshold, even in still-air conditions at 85 °C ambient.
Is TPS7A8033DRBT suitable for a long-production-run industrial design?
Yes. TPS7A8033DRBT was introduced in February 2018 and carries a YTEOL (years to end-of-life) value of 15 years, indicating strong long-term supply commitment from Texas Instruments. Its fixed 3.3 V output and standard VSON-8 footprint also make it straightforward to qualify a second source if supply chain diversification is required.
