TPS2051BDBVR

Texas Instruments · AC-DC Controllers and Regulators · SOT-23-5

TPS2051BDBVR 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 OUT power_out Power-switch output. Delivers current from IN through the internal 70 mΩ high-side N-channel MOSFET to the load; up to 500 mA continuous with a typical 1 A current limit.
2 GND power_in Ground reference for the device.
3 OC output Overcurrent open-drain fault output, active-low. Asserts (pulls low) after a deglitch delay when the switch enters current-limit or thermal-shutdown. Requires an external pull-up resistor.
4 EN input Enable input. On the TPS2051B (205xB series) EN is active-high: logic high turns on the power switch, logic low disables it.
5 IN power_in Input supply voltage, 2.7 V to 5.5 V. Feeds the internal high-side MOSFET and control circuitry; bypass locally with a 0.1 µF capacitor.

CAD (KiCad official)

  • Symbol: TPS2051BDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tps2051bdbvr-etched.step / tps2051bdbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps2051bdbvr.step / tps2051bdbvr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tps2051bdbvr.step 85 KB You want the bare part, or you mark your own boards.
tps2051bdbvr-etched.step 2.3 MB You want the part with TPS2051BDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 567 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 (74 pp, sha256 b8e3d6d124f7aa62, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
