Key Features
- 1 A output current with 0.19 V typical dropout voltage at 6 V input, minimizing power dissipation in automotive always-on rail designs
- High PSRR and low quiescent current for clean supply regulation in noise-sensitive automotive infotainment and ADAS sensor circuits
- AEC-Q100 qualified with -40°C to 125°C operating range and power-good indicator in compact 8-pin SON package
Applications
The TPS74611PQWDRBRQ1 is designed for automotive post-regulator stages that power microcontrollers, sensors, and communication ICs from a 3.3 V or 5 V switched-mode supply in ADAS, infotainment, and body-control modules. Its high PSRR rejects switching noise from adjacent DC-DC converters, preventing interference in sensitive radar, camera, or CAN transceiver supply rails. The power-good output simplifies sequencing between supply domains during vehicle startup and shutdown sequences.

Frequently Asked Questions
What dropout voltage does TPS74611PQWDRBRQ1 exhibit at 1 A load, and how does this affect heat dissipation?
At 1 A output current, TPS74611PQWDRBRQ1 has a typical dropout voltage of 0.19 V and a maximum of 0.79 V. Powering a 1 A load from a 3.6 V input to a 3.3 V output results in only 0.3 W typical dissipation at the nominal dropout, keeping junction temperature well below the 125°C maximum even in an 8-pin SON package without additional heatsinking in most automotive cabin-temperature environments.
What temperature range and automotive qualification does TPS74611PQWDRBRQ1 carry?
TPS74611PQWDRBRQ1 is AEC-Q100 qualified for operation from -40°C to 125°C, meeting the demands of automotive underhood-adjacent and interior electronics. The PQWDRBRQ1 suffix indicates automotive grade with the extended qualification testing required for safety-relevant supply rails in ADAS camera modules, radar front ends, and CAN/LIN transceiver power domains operating across the full automotive temperature range.
How does the power-good output of TPS74611PQWDRBRQ1 assist supply sequencing in multi-rail automotive designs?
The open-drain power-good pin asserts high when the output voltage reaches approximately 92% of its regulated value, providing a digital readiness signal for downstream microcontrollers or FPGAs. In a typical ADAS domain controller, this signal enables a core supply LDO to begin ramping only after the I/O rail from TPS74611 has settled, preventing latch-up conditions that can occur when a 1.8 V core powers up before the 3.3 V I/O supply reaches its nominal level.
Which input voltage range does TPS74611PQWDRBRQ1 support, and can it regulate from a 5 V automotive switched-mode rail?
The LDO accepts input voltages from 1.5 V minimum up to 6 V maximum, with a 6.5 V absolute maximum rating. A 5 V SMPS output feeding TPS74611 to produce a 3.3 V rail at 1 A is a common automotive configuration, resulting in 1.7 V dropout across the LDO and 1.7 W dissipation. This remains within the 8-pin SON thermal limits when the PCB copper pad area is at least 400 mm², as recommended in the datasheet thermal guidelines.
