HT7233-MS from MSKSEMI, 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 | VSS | power_in | Ground reference pin, listed in the datasheet pin table as Ground (VSS). |
| 2 | VIN | power_in | Power input pin; the absolute maximum input voltage VIN is -0.3 V to +15 V, and a 10 µF tantalum input bypass capacitor is recommended. |
| 3 | VOUT | power_out | Regulated output pin for the 3.3 V HT7233-MS, with a minimum 10 µF tantalum output capacitor and ESR below 0.5 Ω required for stability. |
