MT3401A-EN from Magn Tek, in a TO-92S. 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 | VS | power_in | Supply pin; the datasheet specifies an operating supply voltage of 2.8V to 24V, with an absolute maximum of 27V referenced to GND. |
| 2 | GND | power_in | Ground pin; all absolute maximum voltages are referenced to GND. |
| 3 | OUT | output | Open-drain output that turns Low when B exceeds BOP and High when B falls below BRP; continuous output current is limited to 50 mA and output voltage to 27V maximum. |
