78S12M

UNI SEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

78S12M from UNI SEMIC, in a SOT-89. 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 VOUT power_out Regulated 12V output, delivering up to 120 mA with internal current limiting and thermal shutdown.
2 GND power_in Ground reference pin of the regulator; the tab is also labelled GND in the package drawing.
3 VIN power_in Unregulated positive input voltage to the regulator.

  • Symbol: 78S12M
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: 78s12m-etched.step / 78s12m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78s12m.step / 78s12m.glb are the bare package body.
