78M12A

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

78M12A from Slkor SLKORMICRO Elec, 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 Input power_in Unregulated input voltage to the regulator; the datasheet gives absolute maximum input voltages of 35V for VO = 5V to 18V and 40V for VO = 24V.
2 GND power_in Common ground reference for the regulator, carrying the quiescent current (typically 4.0 to 4.2 mA for the 12V version).
3 Output power_out Regulated 12V output (78M12A) rated for up to 0.5A output current, with short-circuit current typically 300 mA and peak current typically 700 mA.

CAD (KiCad official)

  • Symbol: 78M12A
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: 78m12a-etched.step / 78m12a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78m12a.step / 78m12a.glb are the bare package body.
