HMIC5504-3.3YM5-TR

HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

HMIC5504-3.3YM5-TR from HXY MOSFET, in a SOT-23-5L. 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 Unregulated supply input. Absolute max 6V; typical operation Vout+1V up to 6V. Bypass to VSS with a 1-10µF ceramic capacitor.
2 VSS power_in Device ground reference (地). Connect to system ground plane.
3 CE input Chip Enable (使能端). Drive high (up to VIN) to enable the regulator; drive to VSS (0V) to shut the output off and reduce quiescent current to <1µA. Absolute max range VSS-0.3V to VIN+0.3V.
4 NC unconnected No connect (悬空). Leave floating; do not tie to any signal or supply.
5 VOUT power_out Regulated 3.3V output (电源输出端). Delivers up to 300mA (450mA absolute max). Requires a 1-10µF ceramic output capacitor to VSS for stability; no 0.1µF bypass required.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
hmic5504-3-3ym5-tr.step 85 KB You want the bare part, or you mark your own boards.
hmic5504-3-3ym5-tr-etched.step 2.7 MB You want the part with HMIC5504-3.3YM5-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 678 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: HXY MOSFET datasheet (5 pp, sha256 568224394a904510, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
