L7824CV-DG

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

L7824CV-DG from STMicroelectronics, in a TO-220. 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 INPUT power_in Unregulated positive DC input voltage (V_I). For a 24 V output, the input must exceed the dropout voltage; recommended V_I is typically 27 V or higher, up to the 40 V absolute maximum. A ~0.33 uF bypass capacitor to GND close to the pin is recommended.
2 GROUND power_in Common ground reference for the input and the regulated output. Electrically connected to the metal tab of the TO-220 package.
3 OUTPUT power_out Regulated +24 V DC output (V_O). Rated for output currents in excess of 1 A (up to 1.5 A) when properly heat-sunk. A ~0.1 uF output capacitor to GND is recommended to improve transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
l7824cv-dg.step 83 KB You want the bare part, or you mark your own boards.
l7824cv-dg-etched.step 799 KB You want the part with L7824CV-DG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 213 faces against 48 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (58 pp, sha256 25ff0de3b3389122, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
