TP142C33S3L

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

TP142C33S3L from TECH PUBLIC, 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 GND power_in Device ground reference. Connect to system ground plane; also serves as the return for the internal reference and control circuitry.
2 VOUT power_out Regulated 3.3V output of the LDO (±2% accuracy). Capable of sourcing up to 450mA. Requires a ceramic or tantalum output capacitor (typ. 1µF) to GND for stability; discharges via ~100Ω internal path when disabled.
3 VIN power_in Input supply pin, 1.2V to 5.5V operating range (absolute max 6.5V to GND). Requires a 1µF ceramic bypass capacitor to GND placed close to the pin. Dropout is 0.18V at 300mA for VOUT=3.3V.

CAD (KiCad official)

  • Symbol: TP142C33S3L
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tp142c33s3l-etched.step / tp142c33s3l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tp142c33s3l.step / tp142c33s3l.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tp142c33s3l.step 59 KB You want the bare part, or you mark your own boards.
tp142c33s3l-etched.step 2.1 MB You want the part with TP142C33S3L already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 510 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: TECH PUBLIC datasheet (12 pp, sha256 aeefd1ca62f3bc35, retrieved 2026-08-17, tier: lcsc)
  • 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).
