SGM2036S-1.8XN5G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SGM2036S-1.8XN5G from SGMICRO, in a SOT-23-5. 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 Voltage Supply Pin. 1.6V to 5.5V operating range. Bypass with a 1µF or larger ceramic capacitor from IN to GND, placed as close as possible to the pin.
2 GND power_in Ground reference for the regulator.
3 EN input Enable Pin. Drive EN high (VIH ≥ 1.5V) to turn on the regulator; drive low (VIL ≤ 0.4V) to shut it down. Must be pulled high by an external resistor to IN if not used - cannot be left floating.
4 BP passive Reference-Noise Bypass Pin (fixed-voltage version, applies to SGM2036S-1.8). Bypass with an external capacitor CBP (typ. 0.01µF) to reduce output noise and improve PSRR. Place capacitor very close to the pin.
5 OUT power_out Regulator Output Pin. Fixed 1.8V nominal, 300mA guaranteed. Requires a ceramic output capacitor with effective capacitance of 0.5µF to 10µF placed close to the pin for stability and decoupling.

CAD (KiCad official)

  • Symbol: SGM2036S-1.8XN5G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sgm2036s-1-8xn5g-etched.step / sgm2036s-1-8xn5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sgm2036s-1-8xn5g.step / sgm2036s-1-8xn5g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm2036s-1-8xn5g.step 85 KB You want the bare part, or you mark your own boards.
sgm2036s-1-8xn5g-etched.step 3.0 MB You want the part with SGM2036S-1.8XN5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 715 faces against 102 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: SGMICRO datasheet (21 pp, sha256 42987f3d5b8b080a, 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).
