TL391LVDBVR from TEXAS INSTRUMENTS, in a SOT-23-5. 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 | OUT | output | Open-collector comparator output that needs an external pull-up; absolute maximum voltage from GND is -0.3 V to 6 V and the output short-circuit duration is limited to 10 s. |
| 2 | GND | power_in | Ground pin serving as the negative supply (V-) reference; split supplies are supported with V- applied to this pin. |
| 3 | IN- | input | Negative (inverting) comparator input; input voltage range is -0.1 V to 5.6 V from GND and input current is limited to ±10 mA. |
| 4 | IN+ | input | Positive (non-inverting) comparator input; input voltage range is -0.1 V to 5.6 V from GND and input current is limited to ±10 mA. |
| 5 | VCC | power_in | Positive power supply; the recommended supply range is 1.65 V to 5.5 V, with an absolute maximum of 6 V. |
