MIC2288YD5-TR

Microchip · DC-DC Converters · TSOT-23-5

MIC2288YD5-TR from Microchip, in a TSOT-23-5. 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 SW output Switch Node (Input): Internal power bipolar collector. Connects to the external boost inductor and Schottky diode. Rated up to 34V switch voltage, 1A typical / 2A absolute max switch current.
2 GND power_in Ground (Return). Device ground return for both signal and power paths on the SOT-23-5 variant.
3 FB input Feedback (Input): 1.24V output voltage sense node. VOUT = 1.24V x (1 + R1/R2). Feedback input current ~-450nA at VFB = 1.24V.
4 EN input Enable (Input): Logic high (>=1.5V) enables the regulator; logic low (<=0.4V) shuts it down. Absolute max range -0.3V to VIN. Enable pin current ~20uA at VEN=10V.
5 VIN power_in Supply (Input): 2.5V to 10V input voltage rail. Absolute max 12V. Quiescent current ~2.8mA (not switching), shutdown current <1uA.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mic2288yd5-tr.step 85 KB You want the bare part, or you mark your own boards.
mic2288yd5-tr-etched.step 2.4 MB You want the part with MIC2288YD5-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 faces against 102 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: Microchip datasheet (11 pp, sha256 50fa671174731710, retrieved 2026-08-17, tier: lcsc)
  • 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).
