TL331BIDBVR 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 | IN- | input | Negative input terminal for voltage comparison; common-mode input voltage range 0V to VCC-1.5V |
| 2 | GND | power_in | Ground reference |
| 3 | IN+ | input | Positive input terminal for voltage comparison; common-mode input voltage range 0V to VCC-1.5V |
| 4 | OUT | output | Open-collector output that sinks maximum 20mA when IN- exceeds IN+ plus input offset voltage |
| 5 | VCC | power_in | Positive power supply input; operating voltage range 2V to 36V for TL331B and TL391B |
