HX7330 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 | GND | power_in | Chip ground pin (芯片接地端); the datasheet gives no electrical limit for this pin. |
| 2 | VIN | power_in | Start-up input pin (启动输入端) that supplies the regulator; the datasheet states a maximum operating input voltage of 12 V with a 15 V absolute maximum input voltage rating. |
| 3 | VOUT | output | Regulated output pin (芯片输出端) that delivers 3.0 V nominal (2.91 V to 3.09 V at VIN=4 V, IOUT=40 mA) for the HX7330 variant. |
