LM78L05ACZ

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

LM78L05ACZ from Texas Instruments, in a TO-92. 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 OUTPUT power_out Regulated +5.0 V output (VO nom 5.0 V, min 4.75 V / max 5.25 V over temperature). Sources up to 100 mA (typ peak 140 mA). A 0.1 µF ceramic output capacitor to ground is recommended to limit high-frequency noise.
2 GND power_in Common ground reference for the regulator. Carries the quiescent current (typ 3 mA) plus a small fraction of the load current. Should be tied to system ground with a low-impedance return.
3 INPUT power_in Unregulated DC input. Requires VIN >= 7 V (min for line regulation) up to the 35 V absolute maximum. A 0.33 µF input bypass capacitor to ground is recommended when the regulator is located far from the power supply filter.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: LM78L05ACZ
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: lm78l05acz-etched.step / lm78l05acz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm78l05acz.step / lm78l05acz.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm78l05acz.step 27 KB You want the bare part, or you mark your own boards.
lm78l05acz-etched.step 1.4 MB You want the part with LM78L05ACZ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 354 faces against 19 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: Texas Instruments datasheet (21 pp, sha256 ad45dc2ba13862ed, 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).
