TPLP2992IM5X-3.3

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

TPLP2992IM5X-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 voltage. Recommended operating range 2.0V to 24V (absolute max 25V). Bypass with a 1µF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference. Common return for the input supply, output capacitor, and enable input.
3 EN input Enable control input. Drive above VIH (min 1.1V) to enable the regulator; drive below VIL (max 0.4V) to shut down. EN input current ~10nA typ at VEN=27V. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for improved PCB anchoring.
5 VOUT power_out Regulated output, fixed 3.3V (±2%) on this variant, 300mA continuous. Requires a 1µF ceramic or tantalum output capacitor to GND for stability. Typical dropout 0.42V at 100mA.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tplp2992im5x-3-3.step 85 KB You want the bare part, or you mark your own boards.
tplp2992im5x-3-3-etched.step 2.6 MB You want the part with TPLP2992IM5X-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: 643 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 925c4b729ae10061, 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).
