MCP1801T-5002I

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

MCP1801T-5002I from TECH PUBLIC, 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 supply voltage input. Operating range 2.0V to 10.0V; absolute maximum 12V. Bypass with a 1 uF capacitor to GND close to the pin.
2 GND power_in Ground terminal (VSS). Common return for input, output, and shutdown reference. Datasheet labels this pin as VSS in the pinout diagram and GND in the pin function table.
3 SHDN input Active-low shutdown input. Drive high (>= 1.6V, up to VIN) to enable the regulator; drive low (<= 0.25V) to disable output. In shutdown the device draws only ~0.01 uA (typical).
4 NC unconnected No internal connection. May be left floating or tied to GND for improved thermal/EMI performance.
5 VOUT power_out Regulated 5.0V output. Delivers up to 150 mA with typical +/-2% tolerance at 25 degC. Requires a minimum 1 uF output capacitor (ceramic, tantalum, or aluminum electrolytic) for stability.

Ordering variants

Same part, different packaging or reel option.

  • MCP1801T-5002II/OT

CAD (KiCad official)

  • Symbol: MCP1801T-5002I
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: mcp1801t-5002i-etched.step / mcp1801t-5002i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp1801t-5002i.step / mcp1801t-5002i.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mcp1801t-5002i.step 85 KB You want the bare part, or you mark your own boards.
mcp1801t-5002i-etched.step 2.5 MB You want the part with MCP1801T-5002I already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 616 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:
