TLV3231DBVR 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 | Push-pull comparator output; the datasheet gives an output short-circuit current rating of ±100 mA with a short-circuit duration of 10 s maximum. |
| 2 | V- | power_in | Negative supply voltage; the supply span VS = (V+) - (V-) is specified from 2.7 V to 5.5 V (6 V absolute maximum). |
| 3 | IN+ | input | Non-inverting (+) comparator input with rail-to-rail range; the input voltage must stay within (V-) - 0.1 V to (V+) + 0.1 V, and signals more than 0.5 V beyond the rails must be current-limited to 10 mA or less. |
| 4 | IN- | input | Inverting (-) comparator input with rail-to-rail range; the input voltage must stay within (V-) - 0.1 V to (V+) + 0.1 V, and signals more than 0.5 V beyond the rails must be current-limited to 10 mA or less. |
| 5 | V+ | power_in | Positive supply voltage; the supply span VS = (V+) - (V-) is specified from 2.7 V to 5.5 V (6 V absolute maximum). |
