SGM2053-3.3XN6G

SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-6

SGM2053-3.3XN6G from SGMICRO, in a SOT-23-6. 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 VIN power_in Input voltage supply pin, 1.5V to 5.5V operating range (6V absolute max). A 2.2µF or larger ceramic capacitor from VIN to GND is recommended for stability.
2 GND power_in Device ground return. Typical quiescent ground current is 17µA (40µA max) with no load.
3 EN input Enable input. Drive EN high (V_IH ≥ 0.7V) to turn the regulator on; drive low (V_IL ≤ 0.3V) to turn it off. Contains an internal ~0.03µA pull-down current source to ensure the device is off when EN is floated. Absolute max -0.3V to 6V.
4 BP passive Reference-noise bypass pin. Connect an external bypass capacitor C_BP (typically 22nF) to GND to reduce output noise (20µV_RMS typ, 10Hz-100kHz). Absolute max -0.3V to (V_IN + 0.3V).
5 NC unconnected Not connected on the fixed-voltage version (SGM2053-3.3). On the SGM2053-ADJ variant this pin is the ADJ feedback input instead.
6 VOUT power_out Regulated output pin (fixed 3.3V nominal on the -3.3 variant), 500mA guaranteed output current, current-limited at ~980mA typ (550mA min). Requires an output ceramic capacitor with effective capacitance of 1µF to 10µF, placed as close as possible to the pin. Absolute max -0.3V to (V_IN + 0.3V).

  • 3D model files: sgm2053-3-3xn6g-etched.step / sgm2053-3-3xn6g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sgm2053-3-3xn6g.step / sgm2053-3-3xn6g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm2053-3-3xn6g.step 97 KB You want the bare part, or you mark your own boards.
sgm2053-3-3xn6g-etched.step 2.9 MB You want the part with SGM2053-3.3XN6G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 702 faces against 117 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 (12 pp, sha256 77df11f36251ebeb, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
