ADR381ARTZ-R2

Analog Devices · Voltage Reference · SOT-23

ADR381ARTZ-R2 from Analog Devices, in a SOT-23. 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 VIN power_in Supply input for the ADR381, specified from 2.8 V to 18 V, with at least 300 mV of headroom above VOUT at ILOAD ≤ 2 mA.
2 VOUT power_out Precision 2.500 V reference output that can source up to 5 mA; it is short-circuit limited to 25 mA to GND and needs no output capacitor for stability.
3 GND power_in Ground reference pin for the reference, to which the output short-circuit current is referenced.
