# ME6212C30M5G

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

ME6212C30M5G 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 | Input supply pin. Operating input voltage range 2.0 V to 6.0 V (absolute max 6.5 V). Requires a 1 uF ceramic input capacitor to VSS close to the pin. |
| 2 | VSS | power_in | Device ground / return reference for VIN, VOUT, and the CE input threshold. |
| 3 | CE | input | Chip-enable input. Drive high (VCEH >= 1.0 V, referenced to VSS, up to VIN) to enable the regulator; drive low (VCEL <= 0.5 V) to shut it down (shutdown current ~0.1 uA typ). Must not be left floating. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to VSS/VIN per board convention. |
| 5 | VOUT | power_out | Regulated 3.0 V output. Delivers up to 350 mA (typ) with ~100 mV dropout at 100 mA. Requires a 1 uF ceramic output capacitor to VSS for stability; no separate 0.1 uF bypass required. |

## CAD (KiCad official)

- Symbol: `ME6212C30M5G`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `me6212c30m5g-etched.step` / `me6212c30m5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `me6212c30m5g.step` / `me6212c30m5g.glb` are the bare package body.

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`me6212c30m5g.step`](me6212c30m5g.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`me6212c30m5g-etched.step`](me6212c30m5g-etched.step) | 2.4 MB | You want the part with `ME6212C30M5G` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 575 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.
