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.","metaTitle":"ISL21080DIH312Z-TK Voltage Reference, 1.25V Fixed Output","metaDescription":"ISL21080DIH312Z-TK series voltage reference from Renesas.

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."},{"question":"How does ISL21080DIH312Z-TK compare to REF3325?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/ISL21080DIH312Z-TK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/ISL21080DIH312Z-TK when reusing this data.
