TLV803SDBZR

Texas Instruments · Supervisor and Reset ICs · SOT-23

TLV803SDBZR 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 pin (0 V). All voltages are referenced to this pin.
2 RESET output Active-low open-drain RESET output. Driven low when VDD falls below the negative-going threshold VIT- (2.93 V for TLV803S) and remains low for the delay time td (200 ms typ) after VDD exceeds VIT-. Requires a 10 kΩ to 1 MΩ external pull-up; pull-up voltage is not limited to VDD.
3 VDD power_in Supply voltage input. Recommended operating range 1.1 V to 6 V; absolute maximum 7 V. Place a 0.1 µF ceramic bypass capacitor close to this pin. Supply current IDD ≈ 9 µA typ.

CAD (KiCad official)

  • Symbol: TLV803SDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tlv803sdbzr-etched.step / tlv803sdbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv803sdbzr.step / tlv803sdbzr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlv803sdbzr.step 59 KB You want the bare part, or you mark your own boards.
tlv803sdbzr-etched.step 2.1 MB You want the part with TLV803SDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 498 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 (23 pp, sha256 d9ce9027c069e1bd, 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).
