# SY7330

**SY(顺烨)** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

SY7330 from SY(顺烨), in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin of the three-terminal regulator; the datasheet lists it only as GND with no further limits. |
| 2 | VIN | power_in | Regulator input supply pin, rated up to 12V input voltage per the electrical characteristics (absolute maximum supply is VSS+14V). |
| 3 | VOUT | power_out | Regulated 3.0V output (3.0V typ., 2.91V to 3.09V at IOUT=40mA, Ta=25°C) with maximum output current of 250mA. |

## CAD (KiCad official)

- Symbol: `SY7330`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `sy7330-etched.step` / `sy7330-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sy7330.step` / `sy7330.glb` are the bare package body.
