TPS2041BDBVR

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

TPS2041BDBVR 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. Connects to the load through the internal 70 mΩ high-side N-channel MOSFET when EN is asserted. A 0.1 µF ceramic plus bulk (e.g. 22 µF) output capacitor is recommended.
2 GND power_in Device ground reference for the control logic, charge pump, and current-limit circuitry.
3 OC output Overcurrent open-drain output, active-low. Pulled low during current-limit or thermal-shutdown fault; requires an external pull-up resistor. Deglitched to reject transients.
4 EN input Enable input. On the TPS2041B this pin is active-low: driving EN low turns the power switch on; driving high turns it off. CMOS-compatible logic input; do not leave floating.
5 IN power_in Input supply voltage, 2.7 V to 5.5 V. Feeds the high-side MOSFET drain and internal charge pump. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps2041bdbvr.step 85 KB You want the bare part, or you mark your own boards.
tps2041bdbvr-etched.step 2.2 MB You want the part with TPS2041BDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 552 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.
