Product details

Package and footprint

Housed in a standard SOT-23-3 package (also listed as TO-236-3 / SC-59), the ISL21080DIH312Z-TK is a surface-mount part that shares the same three-pin footprint as countless other SOT-23 references. The supplier device package is SOT-23-3, so the PCB land pattern is well established. No surprises for the layout engineer — just a bypass cap on the input and a load cap on the output per the datasheet recommendation.

Lifecycle and compliance

That means it is available through franchised and independent channels without LTB risk. For a BOM line that needs a low-power reference, this part is a safe choice for both new designs and ongoing production.

Frequently asked questions

Is ISL21080DIH312Z-TK RoHS compliant?

Yes, it is ROHS3 compliant.

Can ISL21080DIH312Z-TK be used in 3.3V systems?

Yes. The input voltage range is 2.7V to 5.5V, so a 3.3V rail is well within the operating window. The 1.25V output is below the rail, which is typical for a series reference.

How does ISL21080DIH312Z-TK compare to REF3325?

The REF3325 outputs a fixed 2.5V, while the ISL21080DIH312Z-TK outputs 1.25V. The REF3325 also runs at higher quiescent current (typically 8.5µA) versus the ISL21080's 1.5µA. If your system needs a 2.5V reference and can spare the extra supply current, the REF3325 is a direct alternative; if you need 1.25V or the lowest possible quiescent draw, the ISL21080DIH312Z-TK is the better fit.
