ADP125ARHZ-R7 from Analog Devices, in a MSOP-8-EP. 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 1 µF or greater capacitor. |
| 2 | VOUT | power_out | Regulated output voltage; bypass VOUT to GND with a 1 µF or greater capacitor. |
| 3 | ADJ | input | Feedback node for the error amplifier; connect the midpoint of an external divider from VOUT to GND to set the output voltage between 0.8 V and 5.0 V. |
| 4 | GND | power_in | Ground. |
| 5 | EN | input | Enable input; drive high to turn the regulator on and low to turn it off, and connect to VIN for automatic startup. |
| 6 | NC | unconnected | No connect; this pin is not connected internally. |
| 7 | VIN | power_in | Regulator input supply, 2.3 V to 5.5 V; bypass VIN to GND with a 1 µF or greater capacitor. |
| 8 | VIN | power_in | Regulator input supply, 2.3 V to 5.5 V; bypass VIN to GND with a 1 µF or greater capacitor. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
