TPS76318DBVR

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

TPS76318DBVR 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 Input supply voltage. Recommended operating range 2.7 V to 10 V (absolute max -0.3 V to 10 V). Requires a bypass capacitor to GND.
2 GND power_in Device ground reference terminal. All voltages are measured with respect to this pin.
3 EN input Active-high enable input. VIH typ 1.4 V (max 2 V), VIL max 1.2 V. Driving below 0.5 V places the regulator in shutdown (standby current <2 µA). Absolute max voltage range -0.3 V to VI + 0.3 V.
4 NC unconnected No internal connection on the fixed-voltage TPS76318. (On the adjustable TPS76301 this pin is FB, the feedback voltage sense.)
5 OUT power_out Regulated 1.8 V output, capable of sourcing up to 150 mA continuous. Requires an output capacitor (recommended 4.7 µF or 10 µF) to ground for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps76318dbvr.step 85 KB You want the bare part, or you mark your own boards.
tps76318dbvr-etched.step 2.3 MB You want the part with TPS76318DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 566 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 cd3a22f7b2711b20, 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).
