- Power Good output flag provides real-time output voltage monitoring for system supervisory and sequencing circuits
- Wide 1.5 V to 6 V input range (abs max 6.5 V) in compact 8-SON package (JESD-30: S-PDSO-N8), suitable for 3.3-V and 5-V automotive rail designs
Applications
The TPS74510PQWDRBRQ1 is designed for automotive electronic control units (ECUs), ADAS sensor modules, and infotainment systems requiring a reliable, low-noise power supply from a 12-V automotive rail stepped down through a pre-regulator. Its high PSRR effectively rejects alternator and switching noise on the battery line. The power good output simplifies system power sequencing and fault monitoring in safety-critical automotive designs.

Frequently Asked Questions
Is the TPS74510PQWDRBRQ1 qualified for automotive applications?
Yes, the TPS74510PQWDRBRQ1 carries the AEC-Q100 automotive qualification, indicated by the 'Q1' suffix in its part number. It is rated for a temperature range of -40°C to +125°C, making it suitable for use in automotive ECUs, ADAS modules, body electronics, and infotainment systems operating in harsh thermal environments.
What is the dropout voltage of the TPS74510PQWDRBRQ1?
The TPS74510PQWDRBRQ1 has a nominal dropout voltage of 225 mV and a maximum dropout voltage of 600 mV at the full 500-mA output current. This low dropout enables efficient linear regulation with minimal headroom, which is important in automotive applications where the pre-regulator output may be close to the desired output voltage.
What input voltage range does the TPS74510PQWDRBRQ1 support?
The TPS74510PQWDRBRQ1 supports an input voltage range of 1.5 V to 6 V, with an absolute maximum rating of 6.5 V. This range is well suited for powering the device from a 3.3-V or 5-V rail in automotive systems, and the regulator maintains stable operation over the full -40°C to +125°C temperature range.
What does the power good output on the TPS74510PQWDRBRQ1 do?
The power good (PG) output is an open-drain flag that asserts high when the output voltage is within regulation. It provides a simple signal for system supervisory circuits to confirm the LDO output is stable before enabling downstream loads, facilitating safe power sequencing and protecting sensitive ICs from under-voltage conditions during startup.
What package is the TPS74510PQWDRBRQ1 available in?
The TPS74510PQWDRBRQ1 is available in an 8-pin SON (Small Outline No-lead) package with JESD-30 designation S-PDSO-N8. This compact surface-mount package offers a small PCB footprint with good thermal dissipation due to the exposed pad, making it well suited for space-constrained automotive module designs.
