ADR127AUJZ-REEL7

Analog Devices · Voltage References · TSOT-26

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.
