SGM2033-3.0XN5G

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

SGM2033-3.0XN5G 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. Operating range 1.8V to 5.5V (absolute max -0.3V to 6V). Bypass with a 1µF ceramic capacitor close to the pin (CIN ≥ 0.1µF).
2 GND power_in Device ground reference.
3 EN input Enable pin. Drive high (VIH ≥ 1.5V) to turn on the regulator, low (VIL ≤ 0.4V) to shut it down. Has an internal 0.2µA pull-down current source ensuring the device is off when EN is floated. Must be tied to IN if enable functionality is not used.
4 NC unconnected Not connected (fixed-voltage version). This pin is used as ADJ (feedback input) on the SGM2033-ADJ variant only.
5 OUT power_out Regulated 3.0V output pin, 250mA capability (500mA typ. current limit). Requires an output capacitor with effective capacitance of 0.5µF to 10µF located close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm2033-3-0xn5g.step 85 KB You want the bare part, or you mark your own boards.
sgm2033-3-0xn5g-etched.step 2.9 MB You want the part with SGM2033-3.0XN5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 690 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 (17 pp, sha256 3945d763608faafc, 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).
