S-812C33AUA-C2NT2G from ABLIC, in a SOT-89-3. 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 | VSS | power_in | GND pin, the reference for the input, output and ON/OFF voltage ratings (VIN absolute maximum is VSS - 0.3 V to VSS + 18 V). |
| 2 | VIN | power_in | Input voltage pin; the IC is rated for an input of 16 V max. and the absolute maximum input is VSS - 0.3 V to VSS + 18 V. |
| 3 | VOUT | power_out | Regulated output voltage pin; the absolute maximum output voltage is VSS - 0.3 V to VIN + 0.3 V. |
