HT7550M 24V from PUOLOP, 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). |
| 2 | VIN | power_in | Start-up input pin; the absolute maximum input voltage is -0.3 V to +26 V, and the datasheet specifies a DC input voltage of 24 V maximum. |
| 3 | VOUT | power_out | Chip output pin; for the HT7550M the output is 5.0 V typical (4.850 V to 5.150 V), and an output-to-ground capacitor greater than 2.2 μF, with tantalum recommended, must be used. |
