GM7333K

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

GM7333K from GATEMODE, 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 pin. Operating input range 4.5 V to 40 V (absolute max 45 V). Bypass to GND with a 0.1 μF to 2.2 μF ceramic capacitor for best transient/PSRR performance; an input capacitor is required when line transients exceed 10 V.
2 GND power_in Ground reference pin. Connect directly to the PCB ground plane; the output capacitor ground should return to this pin directly for best regulation and noise performance.
3 EN input Enable input. Drive high (typ ≥1.2 V, up to 40 V) to enable the LDO; drive low (≤0.6 V) to place the device in shutdown (I_SHUTDOWN typ 280 nA). Pin may be left floating to enable the device.
4 NC unconnected No internal connection. Leave floating or tie to GND for mechanical robustness.
5 OUT power_out Regulated 3.3 V output pin (2% accuracy over temperature). Requires a 2.2 μF ceramic output capacitor (ESR 0 Ω-0.2 Ω) for stability; supports up to 200 mA continuous, with current limit at ≥250 mA. Absolute max VOUT = 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
gm7333k.step 85 KB You want the bare part, or you mark your own boards.
gm7333k-etched.step 1.6 MB You want the part with GM7333K already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 391 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: GATEMODE datasheet (16 pp, sha256 1aeb1beb1e5d0bb3, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
