HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TJ5205SF5-5.0 from HTC Korea TAEJIN Tech, 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 Supply input. Operating range 2.5V to 16V; absolute maximum 20V. Bypass with a local capacitor for stability.
2 GND power_in Ground reference for the regulator. Ground pin current ~120uA at 100uA load, up to ~1.3mA at 150mA load.
3 EN input Enable/Shutdown input, CMOS/TTL compatible. Logic high (>=2.0V) enables the regulator; logic low (<=0.4V) or open shuts it down. Absolute max VEN = 20V.
4 BYP passive Reference bypass pin. Optional external capacitor (typ. 470pF) from BYP to GND improves noise performance (output noise ~260 nV/sqrt(Hz)). May be left open if low-noise operation is not required. On the ADJ variant this pin is the ADJ feedback input; on the -5.0 fixed variant it is BYP only.
5 VOUT power_out Regulated 5.0V output, guaranteed up to 150mA. Requires a 2.2uF output capacitor for stability. Better than 1% initial accuracy; current-limited (typ. 320mA).

CAD (KiCad official)

  • Symbol: TJ5205SF5-5.0
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tj5205sf5-5-0-etched.step / tj5205sf5-5-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tj5205sf5-5-0.step / tj5205sf5-5-0.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tj5205sf5-5-0.step 85 KB You want the bare part, or you mark your own boards.
tj5205sf5-5-0-etched.step 2.3 MB You want the part with TJ5205SF5-5.0 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 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:
