TLV809K33DBVR

Texas Instruments · Supervisor and Reset ICs · SOT-23

TLV809K33DBVR from Texas Instruments, in a SOT-23. 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 GND power_in Ground reference. All voltages in the device are referenced to GND.
2 RESET output Active-low reset output. Driven low while VDD is below the 2.93 V (typ) threshold VIT- and held low for the fixed 200 ms delay (td) after VDD rises back above the threshold. Push-pull output; VOH = VDD - 0.4 V at IOH = -2 mA (VDD = 3.3 V), VOL <= 0.4 V at IOL = 2 mA. Output is defined for VDD >= 1.1 V.
3 VDD power_in Supply voltage input, also the monitored rail. Recommended operating range 2 V to 6 V (abs max 7 V). Typical supply current 9 uA at VDD = 2 V. Place a 0.1 uF ceramic bypass capacitor near this pin for stable threshold behavior.

CAD (KiCad official)

  • Symbol: TLV809K33DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tlv809k33dbvr-etched.step / tlv809k33dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv809k33dbvr.step / tlv809k33dbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tlv809k33dbvr.step 59 KB You want the bare part, or you mark your own boards.
tlv809k33dbvr-etched.step 2.4 MB You want the part with TLV809K33DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 574 faces against 69 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 (16 pp, sha256 1a4670730bd9eff5, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
