Product Details

TPS7B6950QDCYRQ1 is the fixed 5 V, 150 mA member of Texas Instruments' automotive TPS7B69-Q1 LDO family, supplied in a four-pin SOT-223 package for battery-connected rails.

Although the device accepts 4 to 40 V, this 5 V option is specified for regulated output from 6.5 V at 1 to 150 mA, so a battery-connected standby rail needs headroom during cranking; its 15 µA typical light-load current limits parked-vehicle drain.

The 2.2 µF minimum ceramic output capacitor and integrated short-circuit and thermal protection help keep the housekeeping rail stable through load changes and wiring faults without a complex external protection network.

This 5 V ordering option is appropriate for standby microcontroller power where a fixed rail is wanted, and its AEC-Q100 Grade 1 rating defines the automotive ambient-temperature envelope to check during board qualification.
