TPS70933QDBVRQ1

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

TPS70933QDBVRQ1 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 to the device. Operating range 2.7 V to 30 V (absolute max 32 V). Bypass with at least a 1-µF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference. All voltages are referenced to this pin.
3 EN input Enable pin. Driving this pin high (VEN(HI) ≥ 0.9 V) enables the regulator; driving low (VEN(LO) ≤ 0.4 V) places the device into low-current shutdown (~150 nA). Can be left floating to enable the device. Maximum voltage must remain below 6.5 V.
4 NC unconnected No internal connection. Leave floating or tie to GND.
5 OUT power_out Regulated 3.3-V output, up to 150 mA. Connect a 2.2-µF (2 µF min, 47 µF max) or greater ceramic capacitor from this pin to ground to assure stability.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tps70933qdbvrq1.step 85 KB You want the bare part, or you mark your own boards.
tps70933qdbvrq1-etched.step 3.0 MB You want the part with TPS70933QDBVRQ1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 712 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 (35 pp, sha256 a70b5d92f3d652b1, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
