HK7350-A from HK, 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 | Ground pin, the common reference for the regulator (SOT89-3/TO-92 pin 1; SOT23-3 pin 1). |
| 2 | VIN | power_in | Regulator input; the datasheet's absolute maximum rating for VIN is 18 V. |
| 3 | VOUT | power_out | Regulated output; the absolute maximum output voltage range is Vss-0.3 V to VIN+0.3 V and output current is rated up to 250 mA. |
