SL7812

Slkor(SLKORMICRO Elec.) · Linear Voltage Regulators (LDO) · TO-220

SL7812 from Slkor(SLKORMICRO Elec.), 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 INPUT power_in Unregulated input voltage; for the SL7812 the datasheet specifies 14.5V to 30V line-regulation range, with absolute maximum of 35V (VOUT up to 18V).
2 GND power_in Ground reference pin common to input and output, per the block diagram.
3 OUTPUT power_out Regulated 12V output (11.52V to 12.48V) delivering up to 1A, with short-circuit current of 250mA typical at VIN=35V.

CAD (KiCad official)

  • Symbol: SL7812
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: sl7812-etched.step / sl7812-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl7812.step / sl7812.glb are the bare package body.
