LM1086T-ADJ

HGSEMI · Linear Voltage Regulators (LDO) · TO-220

LM1086T-ADJ from HGSEMI, in a TO-220. 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 GND/ADJ power_in Ground / adjust pin (地/ADJ) for the LM1086-ADJ; the datasheet gives no further electrical limits for this pin.
2 VOUT power_out Output voltage pin; the adjustable version requires an output capacitor of at least 22 µF tantalum for stability, and stability decreases as output current increases.
3 VIN power_in Input operating voltage pin; the absolute maximum input voltage is 20 V and the recommended operating input voltage is 15 V.

CAD (KiCad official)

  • Symbol: LM1086T-ADJ
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: lm1086t-adj-etched.step / lm1086t-adj-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm1086t-adj.step / lm1086t-adj.glb are the bare package body.
