What are the key features of TPS746135PQWDRBRQ1?
- AEC-Q100 automotive qualification for operation from -40°C to 125°C in demanding under-hood and in-cabin environments
- Ultra-low 0.19 V typical dropout voltage at 1 A output enables efficient regulation from Li-ion or automotive 5 V rails
- Integrated power-good output flag simplifies sequencing logic and system supervisory circuits without extra discrete components
What is TPS746135PQWDRBRQ1 used for?
TPS746135PQWDRBRQ1 targets automotive body control modules, infotainment systems, and ADAS sensor boards that require a stable 3.5 V supply from a 5 V regulated bus. Its high PSRR characteristic effectively suppresses alternator ripple and battery transients up to several megahertz, protecting sensitive RF and analog processing stages. The device also suits 48 V mild-hybrid systems where a downstream 5 V pre-regulator feeds this LDO to power microcontrollers and digital peripherals.

Frequently Asked Questions
Which automotive safety standard qualifies TPS746135PQWDRBRQ1 and over what temperature range does it operate?
TPS746135PQWDRBRQ1 is qualified to AEC-Q100 Grade 1, supporting operation from -40°C to 125°C. This qualification level is suitable for automotive applications in engine compartments and other high-temperature zones where commercial-grade regulators would fail.
How does the 0.19 V typical dropout voltage of TPS746135PQWDRBRQ1 benefit a 5 V to 3.5 V conversion?
With only 0.19 V typical dropout, TPS746135PQWDRBRQ1 maintains regulation at 3.5 V output even when the input drops as low as 3.69 V. This headroom advantage extends battery life in automotive stop-start systems and prevents brown-out resets during engine cranking where the 5 V rail may sag.
What is the maximum continuous output current and how does the 8-SON package help thermal management?
TPS746135PQWDRBRQ1 provides up to 1 A continuous output current. The 8-pin SON (S-PDSO-N8) package includes an exposed pad that transfers heat to the PCB ground plane, enabling sustained 1 A delivery with a junction temperature well within the 125°C limit under typical automotive ambient conditions.
How does the integrated power-good signal simplify multi-rail sequencing in an automotive ECU?
The power-good output of TPS746135PQWDRBRQ1 asserts a logic-high flag when the 3.5 V rail reaches approximately 92% of its target. This allows downstream microcontrollers or FPGAs to hold reset until power is stable, eliminating external supervisory ICs and reducing BOM by at least 1 component per sequenced rail.
