GM1400ARHZ-R7 from GONGMOSEMI, 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 | VOUT | power_out | Regulated output voltage; bypass VOUT to GND with a 2.2 µF or larger capacitor. |
| 2 | SENSE | input | Sense (feedback) input connected to the load; an external resistor divider can set the output above the fixed voltage, and the SENSE pin voltage is 1.22 V for this variant. |
| 3 | BYP/NC | unconnected | Not connected; if this function is not used, do not connect this pin to ground. |
| 4 | GND | power_in | Ground. |
| 5 | EN | input | Enable input: high turns the regulator on and low turns it off; tie EN to VIN for automatic start-up. |
| 6 | NC/SS | input | Soft-start pin: an external capacitor sets the soft-start time (SSTIME = 500 µs + 0.6 × CSS, CSS in farads); leave open for 500 µs typical start-up and do not ground this pin. |
| 7 | BYP/NC | unconnected | Not connected; if this function is not used, do not connect this pin to ground. |
| 8 | VIN | power_in | Regulator input supply, 1.9 V to 40 V; bypass VIN to GND with a 2.2 µF or larger capacitor. |
