TPS7B6933QDBVRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS7B6933QDBVRQ1 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Unregulated input power-supply voltage. Recommended operating range 4 V to 40 V (5.5 V min for 5-V version); absolute maximum 45 V (200 ms transient). Requires a 10 µF input capacitor to GND for stability.
2 NC unconnected No internal connection. May be left floating or tied to GND.
3 GND power_in Ground reference. All device voltages are measured with respect to this terminal.
4 GND power_in Ground reference (second GND pin). Tie to pin 3 GND; also provides thermal conduction path to the PCB copper.
5 OUT power_out Regulated 3.3-V output (±3%). Delivers up to 150 mA with short-circuit current limit (150-500 mA). Requires a 2.2 µF to 100 µF ceramic output capacitor (ESR 1 mΩ to 2 Ω) for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps7b6933qdbvrq1.step 85 KB You want the bare part, or you mark your own boards.
tps7b6933qdbvrq1-etched.step 3.2 MB You want the part with TPS7B6933QDBVRQ1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 762 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (25 pp, sha256 ea25f73e6fdeb0fa, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
