LM7805

YONGYUTAI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263

LM7805 from YONGYUTAI, in a TO-263. 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 IN power_in Unregulated input voltage pin, absolute maximum 35 V, with 7 V to 20 V used for the 5 V output electrical characteristics.
2 GND power_in Ground reference pin for the regulator, shown as terminal 2 in the block diagram and TO-263 pinout.
3 OUT power_out Regulated 5 V output (4.8 V to 5.2 V at Tj=25 C) delivering up to 1.0 A with current limiting and thermal shutdown.

  • Symbol: LM7805
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263 (KiCad packages3D, STEP)
  • 3D model files: lm7805-etched.step / lm7805-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm7805.step / lm7805.glb are the bare package body.
