AP7387-50Y-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

AP7387-50Y-13 from Diodes Incorporated, in a SOT-89. 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 GND power_in Device ground. The SOT-89 tab (pin 2) is the primary heat-sink tab and is also GND; connect both to the ground plane with generous copper for thermal dissipation.
2 VIN power_in Regulator input supply, 5V to 60V (absolute maximum -0.3V to +80V). Bypass with a 1µF ceramic capacitor to GND placed close to the pin. On the SOT-89 (AP7387-XXY-13) variant, VIN is on the large center tab.
3 VOUT power_out Regulated 5.0V fixed output, ±2% accuracy, up to 150mA (current-limit 250mA typ.). Requires a 1µF minimum (10µF typ.) ceramic output capacitor to GND for stability.

CAD (KiCad official)

  • Symbol: AP7387-50Y-13
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: ap7387-50y-13-etched.step / ap7387-50y-13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7387-50y-13.step / ap7387-50y-13.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap7387-50y-13.step 57 KB You want the bare part, or you mark your own boards.
ap7387-50y-13-etched.step 1.8 MB You want the part with AP7387-50Y-13 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 462 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.
