HX7830 from HX hengjiaxing, 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 terminal (接地端) of the regulator; the datasheet gives no separate electrical limit for this pin. |
| 2 | VIN | power_in | Input voltage terminal; the absolute maximum input voltage is 9 V and the electrical characteristics specify VIN up to 8 V. |
| 3 | VOUT | power_out | Regulated output terminal; the absolute maximum output voltage range is Vss-0.3 V to Vin+0.3 V and the absolute maximum output current is 600 mA. |
