# ME6217C33P5G

**MICRONE** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-5

ME6217C33P5G from MICRONE, in a SOT-89-5. 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 | CE | input | Chip enable / ON-OFF control. Drive above VCEH (>=1.5 V) to enable the regulator; drive below VCEL (<=0.3 V) to shut it down (Iq ~0.1 uA). Not internally pulled up or down; must not be left floating. Applying an intermediate voltage (0.3 V to VIN-0.3 V) increases quiescent current. |
| 2 | VSS | power_in | Ground reference for the regulator. Return path for input and output capacitors. Should be connected with a low-impedance trace back to the CIN/CL grounds. |
| 3 | NC | unconnected | No internal connection. Leave floating or tie to VSS on the PCB; do not use as a routing via. |
| 4 | VIN | power_in | Unregulated input supply, 2.0 V to 6.5 V operating range (7.0 V absolute maximum). Requires a >=4.7 uF (10 uF typical) low-ESR input capacitor placed close to the pin for stability. |
| 5 | VOUT | power_out | Regulated 3.3 V output (±1%), up to 800 mA when VIN >= VOUT+1.0 V. Requires a >=4.7 uF (10 uF typical) low-ESR output capacitor to VSS; ESR <=0.5 ohm recommended. Must not exceed VIN+0.3 V to avoid parasitic-diode conduction back to VIN. |

## CAD (KiCad official)

- Symbol: `ME6217C33P5G`
- Footprint: `Package_TO_SOT_SMD:SOT-89-5`
- 3D model: SOT-89-5 (KiCad packages3D, STEP)
- 3D model files: `me6217c33p5g-etched.step` / `me6217c33p5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `me6217c33p5g.step` / `me6217c33p5g.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`me6217c33p5g.step`](me6217c33p5g.step) | 86 KB | You want the bare part, or you mark your own boards. |
| [`me6217c33p5g-etched.step`](me6217c33p5g-etched.step) | 2.1 MB | You want the part with `ME6217C33P5G` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 514 faces against 26 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.
