LM3480IM3X-3.3

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

LM3480IM3X-3.3 from Texas Instruments, in a SOT-23. 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 OUT power_out Regulated output voltage pin. Provides 3.3 V ±5% at up to 100 mA. Requires a 0.1 µF (or larger) output capacitor to GND for stability.
2 IN power_in Input voltage supply pin. Accepts 0 V to 30 V (absolute max 35 V). Must be at least VOUT + 1.2 V (dropout) for regulation; bypass with a 0.1 µF ceramic to GND close to the pin.
3 GND power_in Common ground reference for input and output. Ground pin current is typically 2 mA (4 mA max over temperature) with no load.

Ordering variants

Same part, different packaging or reel option.

  • LM3480IM3X-3.3

The extractor listed these alongside LM3480IM3X-3.3, but they are different parts with different electrical characteristics. Do not order them as substitutes.

CAD (KiCad official)

  • Symbol: LM3480IM3X-3.3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lm3480im3x-3-3-etched.step / lm3480im3x-3-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm3480im3x-3-3.step / lm3480im3x-3-3.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm3480im3x-3-3.step 59 KB You want the bare part, or you mark your own boards.
lm3480im3x-3-3-etched.step 2.4 MB You want the part with LM3480IM3X-3.3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 587 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: Texas Instruments datasheet (23 pp, sha256 c2f080f3e40c62ea, 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).
