HT7333-A-MS from MSKSEMI, 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 regulator. |
| 2 | VIN | power_in | Regulator input pin, rated up to 12 V (VIN maximum 12 V); place the input capacitor close to this pin. |
| 3 | VOUT | power_out | Regulated 3.3 V output for HT7333-A-MS, rated up to 250 mA; the output-to-ground capacitor must be greater than 10 μF (tantalum recommended) and placed close to this pin. |
