ME6221CM5G

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

ME6221CM5G from MICRONE, 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 VIN power_in Power input voltage. Operating range 2.8 V to 18 V (absolute max 18 V). Bypass with a 1 uF or larger tantalum capacitor close to the pin.
2 VSS power_in Device ground reference. Connect to system ground return.
3 CE input Chip enable (ON/OFF control). Drive high (>=1.3 V, up to 18 V) to enable the regulator; drive low (<=0.7 V) to disable and enter standby (ICEL ~0 uA). Input leakage is <=0.1 uA.
4 FB input Feedback voltage input. Regulated internally to the 1.25 V reference. Connect to the midpoint of an external resistor divider from VOUT to VSS to set the output voltage: VOUT = 1.25 * (1 + R1/R2). R2 should be >=100 kOhm for best accuracy.
5 VOUT power_out Regulated output voltage, adjustable 1.25 V to 5.0 V, up to 400 mA (typ) / 550 mA (max) with current-limit at ~600 mA. Requires a >=2.2 uF tantalum output capacitor with ESR <1 Ohm for stability.

Ordering variants

Same part, different packaging or reel option.

  • ME6221CM5G

CAD (KiCad official)

  • Symbol: ME6221CM5G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: me6221cm5g-etched.step / me6221cm5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6221cm5g.step / me6221cm5g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6221cm5g.step 85 KB You want the bare part, or you mark your own boards.
me6221cm5g-etched.step 1.9 MB You want the part with ME6221CM5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 460 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: MICRONE datasheet (10 pp, sha256 2b7a8783ac554210, 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).
