PJ78M05TE

PJSEMI · Linear Voltage Regulators (LDO) · TO-252

PJ78M05TE from PJSEMI, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input voltage pin, rated up to 35 V per the absolute maximum ratings.
2 GND power_in Ground pin; the datasheet gives no separate electrical limit for this pin.
3 VOUT power_out Regulated 5 V output, rated up to 500 mA with internal thermal overload and short-circuit current limiting.

CAD (KiCad official)

  • Symbol: PJ78M05TE
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: pj78m05te-etched.step / pj78m05te-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pj78m05te.step / pj78m05te.glb are the bare package body.
