Quiescent current sits at 26 µA, low enough for always-on modules that stay powered during key-off.
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.
Yes, the TPS7B8833QKVURQ1R2 is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications including under-hood and chassis-mounted electronics.
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.
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.
