SE8736X2-HF

Seaward Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

SE8736X2-HF from Seaward Elec, in a SOT-23-3L. 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 Device ground return. Bypass CIN (10μF) and COUT (10μF) reference this node. Per the ordering-code decoder on page 2, the blank pinout suffix on SE8736X2-HF selects the G-I-O SOT23-3 pin arrangement, placing GND on pin 1.
2 VIN power_in Unregulated input supply, 4.5V to 40V operating range (45V absolute max). Requires a 10μF input capacitor placed as close as possible to this pin; use electrolytic or MLCC with a series resistor per the live-insertion recommendations on page 7.
3 VOUT power_out Regulated 3.6V output (the '36' code in SE8736X2 selects 3.6V per the ordering decoder). Delivers up to 100mA typical (150mA min, current-limited around 350mA). Requires a 10μF MLCC output capacitor (≥1μF minimum for stability).

Two STEP files. Same geometry, different body top:

File Size Use it when
se8736x2-hf.step 59 KB You want the bare part, or you mark your own boards.
se8736x2-hf-etched.step 1.9 MB You want the part with SE8736X2-HF already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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: Seaward Elec datasheet (10 pp, sha256 889589178d598f61, 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).
