SGM2036-2.8YN5G

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

SGM2036-2.8YN5G 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 Regulator input. Supply voltage 1.6V to 5.5V. Bypass with a 1µF capacitor to GND. Absolute maximum -0.3V to 6V.
2 GND power_in Device ground reference.
3 EN input Enable pin with internal pull-down resistor. A logic low reduces supply current to less than 1µA (shutdown). Connect to IN for normal operation. Absolute maximum -0.3V to 6V.
4 BP passive Reference-noise bypass pin (fixed-voltage version, applies to the 2.8V SGM2036-2.8). Bypass with a low-leakage 0.01µF ceramic capacitor placed close to the pin for reduced output noise and high PSRR.
5 OUT power_out Regulator output, fixed 2.8V, up to 300mA. Auto-discharge in disable state quickly pulls VOUT low.

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm2036-2-8yn5g.step 85 KB You want the bare part, or you mark your own boards.
sgm2036-2-8yn5g-etched.step 2.8 MB You want the part with SGM2036-2.8YN5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 675 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 (19 pp, sha256 cf3a1b042c069870, 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).
