HX7344 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 terminal (芯片接地端) for the HX73XX LDO regulator. |
| 2 | VIN | power_in | Input voltage pin; the datasheet gives a maximum input voltage of 15 V (absolute maximum) and states regulation is maintained with VIN up to 12 V. |
| 3 | VOUT | power_out | Regulated output terminal (芯片输出端) that delivers the fixed output voltage, with a stated tolerance of ±3%. |
