GM12045ARDZ-5-R7 from GONGMOSEMI, in a SOIC-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 | OUT | power_out | Regulated output pin; a 10 µF or larger ceramic capacitor must be placed from OUT to GND as close to the pin as possible for stability. |
| 2 | SENSE/ADJ | input | Feedback pin to the error amplifier: SENSE is used for fixed-output versions, while the ADJ pin voltage is 1.21 V relative to GND with an external adjustable output range of 1.21 V to 20 V. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | NC | unconnected | Not connected. |
| 5 | SHDN | input | Shutdown pin: pulling it high enables the device and pulling it low disables it, and it must be tied to IN if the enable function is not needed. |
| 6 | GND | power_in | Ground reference pin. |
| 7 | GND | power_in | Ground reference pin. |
| 8 | IN | power_in | Input pin with a operating range of 1.9 V to 20 V, which needs a 10 µF or larger ceramic capacitor to GND placed as close to the pin as possible. |
