AP1501-5.0

UMW · DC-DC Converters · TO-263-5

AP1501-5.0 from UMW, in a TO-263-5. 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 VIN power_in Positive input supply for the IC switching regulator, 4.5V to 40V operating (45V absolute max). A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply switching currents.
2 Output output Internal switch node. Voltage at this pin switches between (+VIN - VSAT) and approximately -0.5V, with a duty cycle of approximately VOUT/VIN. Connects to the external catch diode and inductor. PCB copper area on this node should be kept to a minimum to reduce coupling to sensitive circuitry.
3 GND power_in Circuit ground reference for the regulator.
4 Feedback input Output voltage feedback input. Senses the regulated output voltage to complete the feedback loop. For fixed-output versions (like AP1501-5.0) it connects directly to VOUT. Absolute max -0.3V to +40V; typical bias current 10nA.
5 ON/OFF input Logic-level shutdown input, active-high (regulator OFF when pulled above ~1.3V, up to 25V max applied; ON when pulled below threshold or left floating). Pulling low drops input supply current to ~80µA standby. Absolute max -0.3V to +40V. If unused, may be tied to GND or left open - regulator remains ON.

Same part, different packaging or reel option.

  • AP1501-5.0

CAD (KiCad official)

  • Symbol: AP1501-5.0
  • Footprint: Package_TO_SOT_SMD:TO-263-5_TabPin6
  • 3D model: TO-263-5 (KiCad packages3D, STEP)
  • 3D model files: ap1501-5-0-etched.step / ap1501-5-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap1501-5-0.step / ap1501-5-0.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ap1501-5-0.step 180 KB You want the bare part, or you mark your own boards.
ap1501-5-0-etched.step 1.8 MB You want the part with AP1501-5.0 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 488 faces against 135 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: UMW datasheet (28 pp, sha256 d716270a9a304615, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
