Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

MD5336 from Shanghai Mingda Microelectronics, in a SOT-89-3. 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 GND power_in Ground / VSS reference for the regulator. Common return for input and output; connect to a single-point ground with CIN and CL returns.
2 VOUT power_out Regulated 3.6 V output (±2%), up to 500 mA. Requires an output capacitor CL ≥ 2.2 µF (tantalum) or ≥ 10 µF (aluminum electrolytic) between VOUT and VSS for stability. VOUT must not exceed VIN+0.3 V (parasitic body diode).
3 VIN power_in Unregulated input supply. Absolute maximum 12 V; recommended operating up to 10 V. Bypass to GND with CIN ≥ 1.0 µF as close to the pin as possible.

CAD (KiCad official)

  • Symbol: MD5336
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: md5336-etched.step / md5336-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); md5336.step / md5336.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
md5336.step 57 KB You want the bare part, or you mark your own boards.
md5336-etched.step 1.1 MB You want the part with MD5336 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 301 faces against 42 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: Shanghai Mingda Microelectronics datasheet (16 pp, sha256 54cbb58cd55dcd8d, 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.
