TL391BIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Open-collector output stage; sinks current when negative input voltage exceeds positive input voltage. |
| 2 | GND | power_in | Ground reference for power supply and signal voltages. |
| 3 | IN- | input | Negative comparator input; absolute maximum input voltage range -0.3 V to 38 V. |
| 4 | IN+ | input | Positive comparator input; absolute maximum input voltage range -0.3 V to 38 V. |
| 5 | VCC | power_in | Positive power supply input; recommended operating supply voltage 2 V to 36 V. |
