HT7533-2AF from FOSAN, in a SOT-89-3L. 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 regulator; the datasheet gives no further function or limit for this pin. |
| 2 | Vi | power_in | Input voltage pin, rated at a maximum of 30 V (Vi absolute maximum), with a typical dropout of 0.1 V. |
| 3 | Vo | power_out | Regulated output pin, specified for an output current of 100 mA in the datasheet ratings (IO 100 mA). |
