TPSPX3819M5-L-3-3

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

TPSPX3819M5-L-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. Operating range 2.0 V to 20 V (absolute max 24 V to GND). Bypass with a ceramic or tantalum capacitor to GND close to the pin.
2 GND power_in Ground reference for the regulator. Connect to system ground plane.
3 EN input Enable control input. Drive above VIH (min 1.1 V) to enable the regulator; drive below VIL (max 0.4 V) to place the device in shutdown. EN input current ~10 nA typical at VEN=27V. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND for board layout convenience.
5 VOUT power_out Regulated output voltage (3.3 V nominal for the -3-3 option, +/-2% accuracy) at up to 500 mA. Requires a ceramic or tantalum output capacitor for stability. Dropout ~0.42 V at 100 mA for 3.3 V output.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tpspx3819m5-l-3-3.step 85 KB You want the bare part, or you mark your own boards.
tpspx3819m5-l-3-3-etched.step 2.8 MB You want the part with TPSPX3819M5-L-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: 689 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 e3f6c61832283900, 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).
