ADR127AUJZ-REEL7 from Analog Devices, in a TSOT-26. 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 | NC | unconnected | No connect; must be left floating. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VIN | power_in | Input supply; ADR127 operates from 2.7 V to 18 V (absolute maximum 20 V to GND), and an optional 0.1 µF capacitor can be added. |
| 4 | VOUT | power_out | Reference output of 1.25 V for the ADR127, able to source 5 mA and sink 2 mA, and needing a 0.1 µF capacitor for stability. |
| 5 | NC | unconnected | No connect. |
| 6 | NC | unconnected | No connect; must be left floating. |
