L78M24CV

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

L78M24CV from STMicroelectronics, 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 OUTPUT output Regulated output voltage pin; L78M24CV delivers a nominal 24 V output (23 to 25 V) at up to 0.5 A when adequately heat-sinked.
2 GROUND power_in Common ground/reference pin; the package metal tab is internally connected to this pin for heatsinking.
3 INPUT power_in Unregulated DC input supply pin; absolute maximum input voltage is 40 V for the 20/24 V output versions.

CAD (KiCad official)

  • Symbol: L78M24CV
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: l78m24cv-etched.step / l78m24cv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l78m24cv.step / l78m24cv.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (45 pp, sha256 aab13a77a9bc7601, retrieved 2026-09-29, tier: lcsc)
  • 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).
