Product details

What this LDO brings to an automotive power rail

Packaged in a TO-252-3 (DPak) with a surface-mount tab for heat sinking, it operates from -40°C to 125°C ambient, which puts it in the under-hood and exterior-mount tier. Quiescent current sits at 26 µA, low enough for always-on modules that stay powered during key-off.

Lifecycle and sourcing — active, no LTB clock ticking

The AEC-Q100 qualification is current, so it can be specified into new automotive BOMs without worrying about a last-time-buy window closing. If you are sourcing for a production run, we can quote against an RFQ with confirmed availability and current pricing — no stock figures here, but the supply channel is open.

Frequently asked questions

Is TPS7B8833QKVURQ1R2 AEC-Q100 qualified for automotive applications?

Yes, the TPS7B8833QKVURQ1R2 is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications including under-hood and chassis-mounted electronics.

What are the functional replacements or equivalents for TPS7B8833QKVURQ1R2?

The TPS7A0218PYCHR is a lower-current (200 mA) alternative with the same positive fixed output and protection features, but its PSRR is 55 dB at 1 kHz versus 70 dB. The TPS7A0313PDBVR is another 200 mA option at 1.3 V output. Neither is a direct pin-for-pin drop-in; verify the package and output voltage before substituting.

What is TPS7B8833QKVURQ1R2's listed PSRR?

The power supply rejection ratio is 70 dB at 1 kHz, which provides strong attenuation of ripple from switching converters or alternator noise on the input rail.
