PJ7805TE

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

PJ7805TE from PJSEMI, in a TO-252. 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 Unregulated positive input voltage. Absolute maximum 35V. Recommended input capacitor Ci = 0.33 µF for stability. For PJ7805TE, VI = 7.5V to 20V for regulation over full load range.
2 GND power_in Ground / common return. Also connected to the exposed tab of the TO-252 package (thermal pad shown in Typical Application Circuit on page 2).
3 VOUT power_out Regulated +5V output. Nominal 5.0V (min 4.75V, max 5.25V) over IO = 5 mA to 1 A, VI = 7.5V to 20V. Supports over 1.5A with adequate heat sinking. Recommended output capacitor Co = 0.1 µF.

CAD (KiCad official)

  • Symbol: PJ7805TE
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: pj7805te-etched.step / pj7805te-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pj7805te.step / pj7805te.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
pj7805te.step 119 KB You want the bare part, or you mark your own boards.
pj7805te-etched.step 1.5 MB You want the part with PJ7805TE already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 397 faces against 83 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 (11 pp, sha256 6a3b2f9a1b2fc9fb, 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).
