Product details

What this regulator does on an automotive rail

PSRR is 53 dB at 1 kHz rolling to 30 dB at 1 MHz.

Quiescent current and always-on loads

Quiescent current is 36 µA typical. For an automotive module that stays powered during key-off (body controller, remote keyless entry receiver), that Iq is low enough to avoid draining the battery over a multi-week parking period. The Enable pin lets the system microcontroller shut the regulator off entirely when the rail is not needed.

Protection and monitoring

Built-in protection covers over-current, over-temperature, and under-voltage lockout (UVLO). The Power Good open-drain output asserts when the output is within regulation — useful for sequencing downstream loads or resetting a microcontroller on power-up. The Enable pin is active-high and can be driven directly from a GPIO or a system supervisor.

Sourcing and lifecycle

It is an automotive-grade part, so it carries the usual PCN and long-lifecycle commitment expected for vehicle programs.

Frequently asked questions

Is TPS74625PQWDRBRQ1 automotive grade?

Yes, it is AEC-Q100 qualified and belongs to TI's Automotive series. The operating temperature range is -40°C to 125°C, covering under-hood and cabin environments.

Does TPS74625PQWDRBRQ1 have a power good pin?

Yes, it includes a Power Good open-drain output. The pin goes high-impedance when the output is within regulation, and pulls low when the output falls below the threshold — useful for sequencing or reset generation.

How does TPS74625PQWDRBRQ1 compare to TPS70612DBVT?

The TPS70612DBVT is a 150 mA LDO with higher PSRR at low frequencies (80 dB at 10 Hz) but lower output current and no Power Good pin. The TPS74625PQWDRBRQ1 delivers 1A with PSRR maintained up to 1 MHz, making it the choice for a higher-current rail that needs ripple rejection from a switching converter.
