AP7380-33Y-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

AP7380-33Y-13 from Diodes Incorporated, 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 GND power_in Device ground reference. Common return for the input, output, and internal control circuitry. Connect directly to the system ground plane; on the SOT89 package the tab (pin 2) shares the die attach and is not brought out as a separate signal.
2 VIN power_in Regulator supply input. Accepts 3.5V to 24V (30V abs max). A 1.0µF ceramic bypass capacitor (CIN) from VIN to GND is recommended close to the pin. On SOT89 this is the large center/tab pin, which also provides the primary thermal path to the PCB copper.
3 VOUT power_out Regulated 3.3V output, 150mA max continuous (current-limited at ~150mA typ). Requires a 1.0µF ceramic COUT to GND for stability; the device is compatible with low-ESR ceramic capacitors. Output accuracy is ±1% of the nominal 3.3V setpoint.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap7380-33y-13.step 57 KB You want the bare part, or you mark your own boards.
ap7380-33y-13-etched.step 2.0 MB You want the part with AP7380-33Y-13 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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: Diodes Incorporated datasheet (13 pp, sha256 02d548c7bf237a29, 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).
