HG7336MK-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 pin (地) that serves as the regulator's common reference. |
| 2 | VIN | power_in | Power supply input pin; the datasheet's absolute maximum input voltage is 0 to +45 V (Note 1), recommended operating range is +2.5 V to +45 V, and a 1 µF to 10 µF polarized input capacitor is recommended close to the pin. |
| 3 | VOUT | power_out | Regulated output pin for fixed output voltages from 1.8 V to 5.0 V, delivering up to 300 mA; it must have a capacitor greater than 1 µF (1 µF to 10 µF recommended, ESR 5 mΩ to 100 mΩ) connected to ground. |
