ME6214A50M3G

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

ME6214A50M3G from MICRONE, in a SOT-23. 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	VSS	power_in	Device ground / return pin. Connect to system 0 V; also the reference for the internal 1.21 V bandgap and the negative terminal of the input and output bypass capacitors (CIN = CL = 1 μF recommended).
2	VOUT	power_out	Regulated voltage output. Fixed 5.0 V (±2%) for this MPN, sourcing up to 300 mA with a typical dropout of 160 mV at 100 mA (3.3 V option; 5.0 V option performance similar in kind). Requires a 1 μF ceramic output capacitor (CL) to VSS for stability.
3	VIN	power_in	Unregulated supply input, 2.0 V to 18 V (absolute-max 18 V). Bypass with a 1 μF ceramic input capacitor (CIN) to VSS placed close to the pin. Must be at least VOUT + dropout to hold regulation.

CAD (KiCad official)

Symbol: ME6214A50M3G
Footprint: Package_TO_SOT_SMD:SOT-23
3D model: SOT-23 (KiCad packages3D, STEP)
3D model files: me6214a50m3g-etched.step / me6214a50m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6214a50m3g.step / me6214a50m3g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me6214a50m3g.step`	59 KB	You want the bare part, or you mark your own boards.
`me6214a50m3g-etched.step`	2.1 MB	You want the part with `ME6214A50M3G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 520 faces against 69 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.
