TPS2553DBVR

Texas Instruments · AC-DC Controllers and Regulators · SOT-23-6

TPS2553DBVR from Texas Instruments, in a SOT-23-6. 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 (2.5 V to 6.5 V). Connect a 0.1 µF or greater ceramic bypass capacitor from IN to GND as close to the IC as possible.
2 GND power_in Ground reference for the device. For WSON package, connect externally to the PowerPAD; on SOT-23 there is no thermal pad.
3 EN input Enable input; logic HIGH turns on the power switch (TPS2553 is active-high; the TPS2552 variant uses active-low EN̄ on the same pin).
4 FAULT output Active-low open-drain fault output; asserted during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up (e.g., 100 kΩ). Continuous sink current rated up to 25 mA.
5 ILIM output Current-limit programming pin. External resistor to GND sets current-limit threshold; recommended 15 kΩ ≤ R_ILIM ≤ 232 kΩ. ILIM source current is limited to 1 mA absolute maximum.
6 OUT power_out Power-switch output. Current-limited high-side switched supply to the downstream load (up to 1.5 A continuous, 1.7 A typical current-limit ceiling).

CAD (KiCad official)

  • Symbol: TPS2553DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tps2553dbvr-etched.step / tps2553dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps2553dbvr.step / tps2553dbvr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (44 pp, sha256 8ab20570d3e126d7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
