MAX6126B21+ from Maxim Integrated, in a MSOP-8. 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 | NR | passive | Noise reduction pin: connect a 0.1µF capacitor to improve wideband noise (60nV/√Hz to 35nV/√Hz at 2.048V output), or leave unconnected if not used. |
| 2 | IN | power_in | Positive power-supply input, which must be within (VOUT + 200mV) to 12.6V for specified operation (absolute maximum +13V). |
| 3 | GND | power_in | Ground reference for the device; all voltages are referenced to GND. |
| 4 | GNDS | power_in | Ground-sense connection for Kelvin sensing: connect to the ground connection at the load, with GNDS limited to -0.3V to +0.3V. |
| 5 | I.C. | unconnected | Internally connected: do not connect anything to this pin. |
| 6 | OUTS | output | Voltage reference sense output, which regulates the voltage at the load and should be shorted to OUTF as close to the load as possible; limited to -0.3V to the lesser of (VIN + 0.3V) or +6V. |
| 7 | OUTF | power_out | Voltage reference force output that supplies load current; bypass with a 0.1µF to 10µF capacitor to GND, placed as close to OUTF as possible, and limited to -0.3V to the lesser of (VIN + 0.3V) or +6V. |
| 8 | I.C. | unconnected | Internally connected: do not connect anything to this pin. |
