MIC5219-3.3YM5-TR

Microchip · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

MIC5219-3.3YM5-TR from Microchip, in a SOT-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 IN power_in Supply Input. Operating input voltage range +2.5V to +12V (absolute max -20V to +20V). Provides the unregulated supply to the LDO pass element.
2 GND power_in Ground return for the regulator. Ground pin current is typically 12 mA at 500 mA load and drops to ~0.05 uA in shutdown.
3 EN input Enable (Input): CMOS/TTL compatible control input. Logic high (>=2.0V) enables the regulator; logic low (<=0.4V) or open puts the device into shutdown (near-zero current draw). Do not leave floating.
4 BYP passive Reference Bypass. Connect an external 470 pF capacitor from BYP to GND to reduce output noise to ~300 nV/sqrt(Hz). May be left open if low-noise performance is not required.
5 OUT power_out Regulator Output. Fixed 3.3V output (+/-1% typical, +/-2% over temperature), 500 mA continuous / 500 mA peak in SOT-23-5. Requires a >=2.2 uF (tantalum recommended) output capacitor for stability.

CAD (KiCad official)

  • Symbol: MIC5219-3.3YM5-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: mic5219-3-3ym5-tr-etched.step / mic5219-3-3ym5-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mic5219-3-3ym5-tr.step / mic5219-3-3ym5-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mic5219-3-3ym5-tr.step 85 KB You want the bare part, or you mark your own boards.
mic5219-3-3ym5-tr-etched.step 2.6 MB You want the part with MIC5219-3.3YM5-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 644 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 (14 pp, sha256 b36f990c91d40c48, 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).
