# ME6209A33PG

**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

ME6209A33PG from MICRONE, in a SOT-89-3. 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 | Ground (0 V) reference for the regulator. |
| 2 | VIN | power_in | Unregulated input supply. Accepts up to 18 V (absolute max). Recommended 10 uF input capacitor (CIN). |
| 3 | VOUT | power_out | Regulated 3.3 V output, ±2% accuracy, up to 250 mA (within package power dissipation). Requires 10 uF output capacitor (COUT) for stability. Dropout ~80 mV at IOUT=40 mA. |

## CAD (KiCad official)

- Symbol: `ME6209A33PG`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89-3 (KiCad packages3D, STEP)
- 3D model files: `me6209a33pg-etched.step` / `me6209a33pg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `me6209a33pg.step` / `me6209a33pg.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`me6209a33pg.step`](me6209a33pg.step) | 57 KB | You want the bare part, or you mark your own boards. |
| [`me6209a33pg-etched.step`](me6209a33pg-etched.step) | 1.8 MB | You want the part with `ME6209A33PG` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 464 faces against 42 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.
