ADR03ARZ-REEL7 from Analog Devices, 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 | NIC | unconnected | No internal connect. |
| 2 | VIN | power_in | Input supply pin; the ADR03 operates from 4.5 V to 36.0 V. |
| 3 | TEMP | output | Temperature sensing terminal that, with an external buffer and a simple resistor network, can be used for temperature sensing and approximation. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | TRIM | input | Trim terminal provided for fine adjustment of the 2.5 V output voltage. |
| 6 | VOUT | output | 2.5 V reference output, with output current up to 10 mA. |
| 7 | NIC | unconnected | No internal connect. |
| 8 | NIC | unconnected | No internal connect. |
