# SSP6206-18NR

**Shanghai Siproin Microelectronics** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

SSP6206-18NR from Shanghai Siproin Microelectronics, 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 | GND | power_in | Ground / VSS reference pin for the LDO. Connect to system ground. |
| 2 | VOUT | power_out | Regulated output voltage pin. For SSP6206-18N, provides fixed 1.8V ±2% at up to 300mA. Requires a 1.0µF ceramic output capacitor (CL) to ground for stability. |
| 3 | VIN | power_in | Unregulated input supply pin, 1.6V to 8V absolute max. Requires a 1.0µF ceramic input capacitor (CIN) to ground. Dropout is 0.28V typ (0.42V max) at 100mA for the 1.8V variant. |

## CAD (KiCad official)

- Symbol: `SSP6206-18NR`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ssp6206-18nr-etched.step` / `ssp6206-18nr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ssp6206-18nr.step` / `ssp6206-18nr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`ssp6206-18nr.step`](ssp6206-18nr.step) | 59 KB | You want the bare part, or you mark your own boards. |
| [`ssp6206-18nr-etched.step`](ssp6206-18nr-etched.step) | 2.4 MB | You want the part with `SSP6206-18NR` 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 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.
