UA78L05ACPK

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

UA78L05ACPK from Texas Instruments, in a SOT-89-3. 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-V output. Typical output 5 V (4.75 V to 5.25 V over full temperature range for the AC grade). Bypass with a 0.1-µF capacitor to COMMON. Rated for up to 100 mA output current.
2 COMMON power_in Ground / common return for the regulator. Reference for both input and output voltages.
3 INPUT power_in Unregulated supply input. Recommended operating range 7 V to 20 V for UA78L05AC; absolute maximum 30 V. Bypass with a 0.33-µF capacitor to COMMON.

CAD (KiCad official)

  • Symbol: UA78L05ACPK
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ua78l05acpk-etched.step / ua78l05acpk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ua78l05acpk.step / ua78l05acpk.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ua78l05acpk.step 57 KB You want the bare part, or you mark your own boards.
ua78l05acpk-etched.step 1.5 MB You want the part with UA78L05ACPK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 397 faces against 42 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 (32 pp, sha256 060989d15f369dee, 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).
