TPLP3985IM5X-3.3

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

TPLP3985IM5X-3.3 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 Input supply pin, 1.2 V to 5.5 V. Bypass to GND with a 1-10 uF ceramic or tantalum capacitor placed close to the pin. Absolute maximum -0.3 V to +6.5 V.
2 GND power_in Ground reference for the regulator. Typical ground current is 15 uA at no load; shutdown ground current is 0.1 uA typ.
3 EN input Enable input. Drive above VIH = 1.0 V (min) to enable the regulator; drive below VIL = 0.4 V (max) to shut down. EN input current is 10 nA typ (100 nA max) at VEN = 5 V. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for improved PCB stability.
5 VOUT power_out Regulated output pin, fixed 3.3 V +/-2% for the -3.3 suffix, up to 300 mA. Dropout typ 0.18 V at 300 mA (VOUT >= 3 V). Bypass to GND with a 1-10 uF ceramic or tantalum capacitor. When disabled, an internal ~100 ohm discharge resistor pulls VOUT to GND.

Ordering variants

Same part, different packaging or reel option.

  • TPLP3985IM5X-3.3

CAD (KiCad official)

  • Symbol: TPLP3985IM5X-3.3
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tplp3985im5x-3-3-etched.step / tplp3985im5x-3-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tplp3985im5x-3-3.step / tplp3985im5x-3-3.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tplp3985im5x-3-3.step 85 KB You want the bare part, or you mark your own boards.
tplp3985im5x-3-3-etched.step 2.8 MB You want the part with TPLP3985IM5X-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: 676 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: TECH PUBLIC datasheet (8 pp, sha256 fc0454119164a4d0, 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).
