LM397MF 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 | VIN- | power_in | Inverting input for voltage comparison with input common-mode voltage range 0 V to VS - 1.5 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | VIN+ | power_in | Noninverting input for voltage comparison with input common-mode voltage range 0 V to VS - 1.5 V. |
| 4 | OUTPUT | output | Open-collector output capable of sinking 6 to 13 mA with output low voltage of 180 to 400 mV at 25°C. |
| 5 | VS | power_in | Positive supply voltage with operating range 5 V to 30 V. |
