# ME6215C33M5G

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

ME6215C33M5G 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 | Unregulated power input. Accepts 2.8V to 18V (absolute max 18V). Bypass to VSS with a 1μF ceramic (CIN) close to the pin. |
| 2 | VSS | power_in | Ground / negative supply reference for the regulator. |
| 3 | CE | input | Chip Enable, active high. Drive ≥1.3V to enable the regulator output; drive ≤0.8V to shut down (stand-by current ~0μA). CE pin voltage range is VSS-0.3V to VIN+0.3V. Do not leave floating. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS for improved mechanical robustness. |
| 5 | VOUT | power_out | Regulated 3.3V ±2% output. Delivers up to 300mA (typ) with 160mV dropout at 100mA / 320mV at 200mA. Requires a 1μF ceramic (COUT) to VSS for stability. Short-circuit current limited to ~25mA (typ) via foldback protection. |

## CAD (KiCad official)

- Symbol: `ME6215C33M5G`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `me6215c33m5g-etched.step` / `me6215c33m5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `me6215c33m5g.step` / `me6215c33m5g.glb` are the bare package body.

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`me6215c33m5g.step`](me6215c33m5g.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`me6215c33m5g-etched.step`](me6215c33m5g-etched.step) | 2.4 MB | You want the part with `ME6215C33M5G` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 583 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.
