HT7350-A-MS from MSKSEMI, in a SOT-23. 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 pin (接地脚) of the regulator, shared between input and output return. |
| 2 | VIN | power_in | Input pin; the datasheet's maximum input voltage is 12 V, and the input should be decoupled with a capacitor placed close to the VIN pin. |
| 3 | VOUT | power_out | Regulated output for the HT7350-A-MS at 5.0 V, rated for output current up to 250 mA; the output-to-ground needs a capacitor larger than 10 µF (tantalum recommended). |
