LM397M5 from HGSEMI, 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; the common-mode input voltage range is 0 V to VS - 1.5 V (at 25°C), and the input must not go more than 0.3 V below the negative rail. |
| 2 | GND | power_in | Ground reference pin for the comparator. |
| 3 | VIN+ | power_in | Noninverting input; the common-mode input voltage range is 0 V to VS - 1.5 V (at 25°C), and the input must not go more than 0.3 V below the negative rail. |
| 4 | OUTPUT | output | Open-collector grounded-emitter NPN output that requires an external pullup resistor to the supply and can sink approximately 10 mA. |
| 5 | VS | power_in | Positive supply pin; single supply 5 V to 30 V or split supplies are supported. |
