Procurement Notes
Verify the specific suffix 'W' indicates automotive qualification and 'B' denotes the ±0.1% accuracy grade. Confirm the 'R7' suffix corresponds to the reel packaging format. Ensure the component matches the RT-SOT-23-3 outline dimensions specified in the datasheet for proper PCB footprint compatibility.
Selection Notes
Select this component when a stable 2.5 V reference is required in a small form factor. The automotive qualification makes it suitable for vehicle electronics. Consider the minimum operating current of 50 µA for low-power designs. Verify that the bias resistor selection accommodates the full input voltage and load current variations to maintain regulation within the 15 mA maximum limit.
Part Context
This part belongs to the ADR504x family of precision shunt voltage references, which includes variants with different output voltages such as 2.048 V, 3.0 V, 4.096 V, and 5.0 V.
