PJ71K50SC

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

PJ71K50SC from PJSEMI, 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 Ground reference for the regulator. Connect to system ground / common return.
2 VOUT power_out Regulated 5.0V output (±5%). Delivers up to 20mA (30mA typ.). A 10uF output capacitor to GND is recommended for stability.
3 VIN power_in Unregulated supply input. Operating range up to 24V (absolute max 28V). For 5.0V output, VIN must be at least ~6V (dropout ~100mV at 1mA). A 10uF input capacitor to GND is recommended.

Ordering variants

Same part, different packaging or reel option.

  • PJ71K50SC

CAD (KiCad official)

  • Symbol: PJ71K50SC
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pj71k50sc-etched.step / pj71k50sc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pj71k50sc.step / pj71k50sc.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
pj71k50sc.step 59 KB You want the bare part, or you mark your own boards.
pj71k50sc-etched.step 1.6 MB You want the part with PJ71K50SC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 386 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: PJSEMI datasheet (7 pp, sha256 112f003d9dfd0957, 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).
