MT8691A 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 | Vcc | power_in | Supply input, with an operating range of 2.0 V to 5.5 V and an absolute maximum supply voltage of 7 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | OUT | output | Push-pull output, with an absolute maximum output voltage of 7 V and a maximum continuous output current of 8 mA; the low-level output voltage is at most 0.4 V at 5 mA. |
