HT7144-1 from FOSAN, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference, provides the negative return path for the regulator. |
| 2 | Vi | power_in | Input voltage supply with operating range of 5.4 V to 24 V and absolute maximum rating of 30 V. |
| 3 | Vo | power_out | Regulated output voltage of 4.4 V nominal (4.312-4.488 V range) at IO=10 mA and VI=6.4 V, capable of supplying up to 100 mA. |
