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.
