AP7361C-33ER-13

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223R

AP7361C-33ER-13 from Diodes Incorporated, in a SOT-223R. 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 and thermal reference. Also connected to the tab.
2 OUT power_out Regulated 3.3V output. Bypass to ground through at least a 2.2µF ceramic capacitor; larger COUT improves AC load response. Max continuous output current 1A; internal current limit ~1.5A typ; short-circuit current ~400mA.
3 IN power_in Regulator input supply, 2.2V to 6.0V recommended (absolute max 6.5V). Bypass to ground through at least a 1µF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: AP7361C-33ER-13
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223R (KiCad packages3D, STEP)
  • 3D model files: ap7361c-33er-13-etched.step / ap7361c-33er-13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7361c-33er-13.step / ap7361c-33er-13.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap7361c-33er-13.step 64 KB You want the bare part, or you mark your own boards.
ap7361c-33er-13-etched.step 2.6 MB You want the part with AP7361C-33ER-13 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 632 faces against 75 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.
