HG7330MK-1 from HGSEMI, in a SOT-89. 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 | Ground reference pin for the LDO. |
| 2 | VIN | power_in | Power input pin, with absolute maximum input voltage of 0 to +45 V and recommended operating input of +2.5 V to +45 V, using a 1 to 10 uF polarized capacitor placed close to the pin. |
| 3 | VOUT | power_out | Regulated output pin that must have a capacitor larger than 1 uF to ground (1 to 10 uF polarized recommended, ESR 5 to 100 mΩ), rated for output currents of 0 to 300 mA. |
