SL7603P33M5R

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SL7603P33M5R from Slkor SLKORMICRO Elec, 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 VIN power_in Unregulated input supply pin. Operating range 3.5V to 15V (absolute max 18V). Bypass to GND with a 1uF input capacitor close to the pin.
2 GND power_in Ground / Vss return pin for the regulator. Connect to the system ground plane.
3 CE input Chip Enable input. Drive high to enable the regulator output; drive low to disable. Present only on the SOT23-5 variant.
4 NC unconnected No-connect pin. Leave floating or tie to ground; no internal connection specified.
5 VOUT power_out Regulated 3.3V output pin, ±2% accuracy. Rated for up to 500mA output current. Requires a 1uF tantalum or 6.8uF ceramic output capacitor for stability.

CAD (KiCad official)

  • Symbol: SL7603P33M5R
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sl7603p33m5r-etched.step / sl7603p33m5r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl7603p33m5r.step / sl7603p33m5r.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sl7603p33m5r.step 85 KB You want the bare part, or you mark your own boards.
sl7603p33m5r-etched.step 2.6 MB You want the part with SL7603P33M5R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 609 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: Slkor SLKORMICRO Elec datasheet (9 pp, sha256 dab498b6c14d8f23, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
