A1126LUA-T from Allegro MicroSystems, LLC, 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 | VCC | power_in | Connects the power supply to the chip; operating supply voltage is 3 to 24 V with TJ below 165°C, and forward supply voltage is rated to 28 V. |
| 2 | GND | power_in | Ground connection for the device. |
| 3 | VOUT | output | Open-drain output that switches low when the operate point is reached, sinking up to the output current limit IOM of 30 to 60 mA, with output off voltage rated to 28 V. |
