ADR5044BRTZ-REEL7 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 | V+ is the positive terminal of the shunt reference, fed from the supply through RBIAS, and the device operates with input current from 50 µA to 15 mA. |
| 2 | V- | power_in | V- is the negative (reference common) terminal of the shunt reference, with a maximum reverse current of 25 mA stated in the absolute maximum ratings. |
| 3 | T | passive | Pin 3 is printed as 'T' in the figure text, and the datasheet recommends connecting it to V+. |
