MCP1501-25E from Microchip Tech, 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 | VDD | power_in | Power supply input that also serves as the input voltage for the voltage reference; refer to the Electrical Tables for the minimum voltage for the device. |
| 2 | GND | power_in | System ground, the power supply return, to be connected to system ground. |
| 3 | SHDN | input | Active-low digital shutdown input that places the device in shutdown (output driver tristated); the device should be allowed to power up before using this feature. |
| 4 | GND | power_in | System ground, the power supply return, to be connected to system ground. |
| 5 | GND | power_in | System ground, the power supply return, to be connected to system ground. |
| 6 | GND | power_in | System ground, the power supply return, to be connected to system ground. |
| 7 | OUT | output | Buffered voltage reference output, to be connected to the FEEDBACK pin at the device on the SOIC package; the output driver is tristated in shutdown. |
| 8 | FEEDBACK | input | Buffer amplifier feedback pin, to be connected to the OUT pin at the device on the SOIC package; it accurately holds the output voltage if there is routing impedance or IR-drop between OUT and FEEDBACK. |
