Product details

1.6V fixed rail for automotive electronics

The Texas Instruments TPS76316QDBVRG4Q1 is a single-output, positive-voltage LDO regulator delivering a fixed 1.6V at up to 150mA.

PSRR and noise rejection — what 60 dB at 1 kHz buys you

The 60dB PSRR at 1kHz attenuates ripple from a switching pre-regulator or alternator noise.

Protection set: over-current, over-temperature, reverse polarity

Three integrated protections cover common failure modes. Over-current limits the output during a short; thermal shutdown prevents die damage; reverse polarity blocks damage from reversed battery connection.

Supplied in a SOT-23-5 package, surface-mount only. The footprint is standard for small LDOs.

The TPS76316QDBVRG4Q1 is an active, current-production part with no last-time-buy or obsolescence notice. It is ROHS3 compliant and carries full AEC-Q100 automotive qualification. For dual-sourcing or a pin-compatible alternate with slightly different protection features, the TPS70612DBVT is a validated second source — same package, same 150mA capability, but its fixed output is 1.2V.

Frequently asked questions

Is TPS76316QDBVRG4Q1 a fixed output regulator?

Yes, the output is fixed at 1.6V. There is no adjustable version in this package variant.

What are the equivalents or substitutes for TPS76316QDBVRG4Q1?

The TPS70612DBVT is a pin-compatible alternative with a fixed 1.2V output and broader PSRR (80dB to 52dB). For a 1.8V fixed output at 200mA, consider the TPS7A0218PYCHR. Both are AEC-Q100 qualified and share the same SOT-23-5 footprint.
