Product Details

TPS7B6933QDCYRQ1 is Texas Instruments' fixed 3.3 V, 150 mA automotive LDO in a four-pin DCY SOT-223 package.

Its 4 V to 40 V input range accommodates a high-voltage vehicle rail, but TI specifies rated 3.3 V output accuracy across the full 150 mA load range from 5 V input upward.

The 15 µA typical light-load quiescent current suits a standby microcontroller supply, where the regulator remains powered while the rest of the electronics are asleep.

A low-ESR ceramic output capacitor supports loop stability, and short-circuit and thermal protection help contain faults at the regulated load.

The 33 ordering segment fixes the output at 3.3 V, distinguishing it from this family's 2.5 V and 5 V versions.
