MCP1702T-3302E

Microchip · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23A-3

MCP1702T-3302E from Microchip, in a SOT-23A-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 reference for the regulator. Connect directly to the system ground plane.
2 VOUT power_out Regulated output voltage pin, nominal 3.3V for the -3302 option. Delivers up to 250 mA (VR ≥ 2.5V). Requires a 1 µF (min) to 22 µF ceramic, tantalum, or aluminum electrolytic output capacitor for stability.
3 VIN power_in Unregulated supply input. Operating range 2.7V to 13.2V; absolute maximum 14.5V. Requires VIN ≥ VOUT(MAX) + VDROPOUT(MAX). A 1 µF ceramic input capacitor is recommended.

Two STEP files. Same geometry, different body top:

File Size Use it when
mcp1702t-3302e.step 59 KB You want the bare part, or you mark your own boards.
mcp1702t-3302e-etched.step 2.4 MB You want the part with MCP1702T-3302E already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 571 faces against 69 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: Microchip datasheet (26 pp, sha256 eebbb32821ad97ab, retrieved 2026-08-17, tier: manufacturer)
  • 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).
