APX803L20-26SA-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23-3

APX803L20-26SA-7 from Diodes Incorporated, in a SOT-23-3. 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 for the supervisor. Absolute-max VCC referenced to this pin is -0.3 to 6.0V.
2 RESET output Reset output, active-low open-drain. Asserts low whenever VCC falls below the 2.6V threshold and remains asserted for the tDELAY timeout (220ms typ for the L20 option) after VCC recovers. Requires an external pull-up (100kΩ shown in typical application). VOL ≤ 0.4V at ISINK = 3.5mA; max sink capability ~20mA.
3 VCC power_in Operating voltage input and monitored supply. Recommended operating range 0.9V to 5.5V; absolute max 6.0V. This is the supply whose level is compared against the internal 2.6V threshold.

File Size Use it when
apx803l20-26sa-7.step 59 KB You want the bare part, or you mark your own boards.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 661 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: Diodes Incorporated datasheet (22 pp, sha256 849cd25d6fd15081, retrieved 2026-08-17, tier: lcsc)
  • 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).
