AD1580BRTZ-R2 from Analog Devices, in a SOT-23-3. 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 | V+ | power_in | Positive terminal of the 2-terminal shunt reference, which carries the reverse current (50 µA to 10 mA) and develops the 1.225 V output across V+ and V-. |
| 2 | V- | power_in | Negative (common) terminal of the 2-terminal shunt reference, forming the 1.225 V reference with V+. |
| 3 | NC (OR V-) | unconnected | No connect in the SOT-23 pinout; the datasheet notes this pin may alternatively be tied to V-. |
