7812

HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L

7812 from HXY MOSFET, in a TO-252-2L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Unregulated positive supply input. Maximum input voltage 35V; typical operation with VIN = 14.5V to 30V for 12V output. Bypass with 0.33μF ceramic capacitor to GND close to the pin.
2 GND power_in Ground reference for both input and output. In TO-252-2L this pin is also the exposed tab, providing the primary thermal path to the PCB copper pour.
3 OUT power_out Regulated +12V output (11.64V-12.36V typ. at TJ=25°C). Delivers >500mA continuous; peak ~0.7A. Bypass with 0.1μF ceramic capacitor to GND for stability and transient response.

  • 3D model: TO-252-2L (KiCad packages3D, STEP)
  • 3D model files: 7812-etched.step / 7812-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 7812.step / 7812.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HXY MOSFET datasheet (5 pp, sha256 7d0a13ebf7baffbf, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
